How can I create an executable JAR with dependencies using Maven

Question

I want to package my project in a single executable JAR for distribution   How can I make a Maven project package all dependency JARs into my output JAR

You can use maven-dependency-plugin  but the question was how to create an executable JAR  To do that requires the following alteration to Matthew Franglen s response  btw  using the dependency plugin takes longer to build when starting from a clean target     lt build gt       lt plugins gt           lt plugin gt               lt artifactId gt maven-jar-plugin lt  artifactId gt               lt configuration gt                   lt archive gt                       lt manifest gt                           lt mainClass gt fully qualified MainClass lt  mainClass gt                       lt  manifest gt                   lt  archive gt               lt  configuration gt           lt  plugin gt           lt plugin gt               lt artifactId gt maven-dependency-plugin lt  artifactId gt               lt executions gt                   lt execution gt                       lt id gt unpack-dependencies lt  id gt                       lt phase gt package lt  phase gt                       lt goals gt                           lt goal gt unpack-dependencies lt  goal gt                       lt  goals gt                   lt  execution gt               lt  executions gt           lt  plugin gt       lt  plugins gt       lt resources gt           lt resource gt               lt directory gt   basedir  target dependency lt  directory gt           lt  resource gt       lt  resources gt   lt  build gt

You can use the dependency-plugin to generate all dependencies in a separate directory before the package phase and then include that in the classpath of the manifest    lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-dependency-plugin lt  artifactId gt       lt executions gt           lt execution gt               lt id gt copy-dependencies lt  id gt               lt phase gt prepare-package lt  phase gt               lt goals gt                   lt goal gt copy-dependencies lt  goal gt               lt  goals gt               lt configuration gt                   lt outputDirectory gt   project build directory  lib lt  outputDirectory gt                   lt overWriteReleases gt false lt  overWriteReleases gt                   lt overWriteSnapshots gt false lt  overWriteSnapshots gt                   lt overWriteIfNewer gt true lt  overWriteIfNewer gt               lt  configuration gt           lt  execution gt       lt  executions gt   lt  plugin gt   lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-jar-plugin lt  artifactId gt       lt configuration gt           lt archive gt               lt manifest gt                   lt addClasspath gt true lt  addClasspath gt                   lt classpathPrefix gt lib  lt  classpathPrefix gt                   lt mainClass gt theMainClass lt  mainClass gt               lt  manifest gt           lt  archive gt       lt  configuration gt   lt  plugin gt    Alternatively use   project build directory  classes lib as OutputDirectory to integrate all jar-files into the main jar  but then you will need to add custom classloading code to load the jars

The maven-assembly-plugin worked great for me  I spent hours with the maven-dependency-plugin and couldn t make it work  The main reason was that I had to define in the configuration section explicitly the artifact items which should be included as it is described in the documentation   There is an example there for the cases when you want to use it like  mvn dependency copy  where there are not included any artifactItems but it doesn t work

I compared the tree plugins mentioned in this post  I generated 2 jars and a directory with all the jars  I compared the results and definitely the maven-shade-plugin is the best  My challenge was that I have multiple spring resources that needed to be merged  as well as jax-rs  and JDBC services  They were all merged properly by the shade plugin in comparison with the maven-assembly-plugin  In which case the spring will fail unless you copy them to your own resources folder and merge them manually one time  Both plugins output the correct dependency tree  I had multiple scopes like test provide  compile  etc the test and provided were skipped by both plugins  They both produced the same manifest but I was able to consolidate licenses with the shade plugin using their transformer  With the maven-dependency-plugin of course you don t have those problems because the jars are not extracted  But like some other have pointed you need to carry one extra file s  to work properly  Here

I tried the most up-voted answer here  and was able to get the jar runnable  But the program didn t run correctly  I do not know what the reason was  When I try to run from Eclipse  I get a different result but when I run the jar from command-line I get a different result  it crashes with a program-specific runtime error    I had a similar requirement as the OP just that I had too many  Maven  dependencies for my project  Fortunately  the only solution that worked for me was that using Eclipse  Very simple and very straightforward  This is not a solution to the OP but is a solution for someone who has a similar requirement but with many Maven dependencies   1  Just right-click on your project folder  in Eclipse  and select Export  2  Then select Java -  Runnable Jar  3  You will be asked to choose the location of the jar file  4  Finally  select the class that has the Main method that you want to run and choose Package dependencies with the Jar file and click Finish

Okay  so this is my solution  I know it s not using the pom xml file  But I had the problem my programmme compiling and running on Netbeans but it failing when I tried Java -jar MyJarFile jar  Now  I don t fully understand Maven and I think this why was having trouble getting Netbeans 8 0 2 to include my jar file in a library to put them into a jar file  I was thinking about how I used to use jar files with no Maven in Eclipse    It s Maven that can compile all the dependanices and plugins  Not Netbeans   If you can get Netbeans and be able to use java  jar to do this please tell me how      v     Solved - for Linux  by opening a terminal    Then  cd  MyRootDirectoryForMyProject   Next  mvn org apache maven plugins maven-compiler-plugin compile   Next  mvn install   This will create jar file in the target directory   MyJarFile-1 0-jar-with-dependencies jar   Now  cd target    You may need to run  chmod  x MyJarFile-1 0-jar-with-dependencies jar   And finally  java -jar MyJarFile-1 0-jar-with-dependencies jar   Please see   https   cwiki apache org confluence display MAVEN LifecyclePhaseNotFoundException  I ll post this solution in on a couple of other pages with a similar problem  Hopefully I can save somebody from a week of frustration

I won t answer directly the question as other have already done that before  but I really wonder if it s a good idea to embed all the dependencies in the project s jar itself   I see the point  ease of deployment   usage  but it depends of the use case of your poject  and there may be alternatives  see below     If you use it fully standalone  why not   But if you use your project in other contexts  like in a webapp  or dropped in a folder where other jars are sitting   you may have jar duplicates in your classpath  the ones in the folder  the one in the jars   Maybe not a bid deal but i usually avoid this   A good alternative     deploy your application as a  zip    war   the archive contains your project s jar and all dependent jars   use a dynamic classloader mechanism  see Spring  or you can easily do this yourself  to have a single entry point of your project  a single class to start - see the Manifest mechanism on another answer   which will add  dynamically  to the current classpath all the other needed jars    Like this  with in the end just a manifest and a  special dynamic classloader main   you can start your project with    java -jar ProjectMainJar jar com stackoverflow projectName MainDynamicClassLoaderClass

Ken Liu has it right in my opinion  The maven dependency plugin allows you to expand all the dependencies  which you can then treat as resources  This allows you to include them in the main artifact  The use of the assembly plugin creates a secondary artifact which can be difficult to modify - in my case I wanted to add custom manifest entries  My pom ended up as    lt project gt         lt build gt     lt plugins gt      lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-dependency-plugin lt  artifactId gt       lt executions gt        lt execution gt         lt id gt unpack-dependencies lt  id gt         lt phase gt package lt  phase gt         lt goals gt          lt goal gt unpack-dependencies lt  goal gt         lt  goals gt        lt  execution gt       lt  executions gt      lt  plugin gt     lt  plugins gt           lt resources gt      lt resource gt       lt directory gt   basedir  target dependency lt  directory gt       lt targetPath gt   lt  targetPath gt      lt  resource gt     lt  resources gt    lt  build gt        lt  project gt

This blog post shows another approach with combining the maven-jar and maven-assembly plugins  With the assembly configuration xml from the blog post it can also be controlled if dependencies will be expanded or just be collected in a folder and referenced by a classpath entry in the manifest      The ideal solution is to include the jars in a lib folder and the manifest mf file of the main jar include all the jars in classpath    And exactly that one is described here  https   caffebig wordpress com 2013 04 05 executable-jar-file-with-dependent-jars-using-maven

Problem with locating shared assembly file with maven-assembly-plugin-2 2 1   Try using descriptorId configuration parameter instead of descriptors descriptor or descriptorRefs descriptorRef parameters   Neither of them do what you need  look for the file on classpath  Of course you need adding the package where the shared assembly resides on maven-assembly-plugin s classpath  see below   If you re using Maven 2 x  not Maven 3 x   you may need adding this dependency in top-most parent pom xml in pluginManagement section   See this for more details   Class  org apache maven plugin assembly io DefaultAssemblyReader  Example            lt  -- Use the assembly plugin to create a zip file of all our dependencies  -- gt           lt plugin gt               lt artifactId gt maven-assembly-plugin lt  artifactId gt               lt version gt 2 2 1 lt  version gt               lt executions gt                   lt execution gt                       lt id gt make-assembly lt  id gt                       lt phase gt package lt  phase gt                       lt goals gt                           lt goal gt single lt  goal gt                       lt  goals gt                       lt configuration gt                           lt descriptorId gt assembly-zip-for-wid lt  descriptorId gt                       lt  configuration gt                   lt  execution gt               lt  executions gt               lt dependencies gt                   lt dependency gt                       lt groupId gt cz ness ct ip assemblies lt  groupId gt                       lt artifactId gt TEST SharedAssemblyDescriptor lt  artifactId gt                       lt version gt 1 0 0-SNAPSHOT lt  version gt                   lt  dependency gt               lt  dependencies gt           lt  plugin gt

Use the maven-shade-plugin to package all dependencies into one uber-jar  It can also be used to build an executable jar by specifying the main class  After trying to use maven-assembly and maven-jar   I found that this plugin best suited my needs    I found this plugin particularly useful as it merges content of specific files instead of overwriting them  This is needed when there are resource files that are have the same name across the jars and the plugin tries to package all the resource files  See example below          lt plugins gt       lt  -- This plugin provides the capability to package the artifact in an uber-jar  including its dependencies and to shade - i e  rename - the packages of some of the dependencies  -- gt           lt plugin gt               lt groupId gt org apache maven plugins lt  groupId gt               lt artifactId gt maven-shade-plugin lt  artifactId gt               lt version gt 1 4 lt  version gt               lt executions gt                   lt execution gt                       lt phase gt package lt  phase gt                       lt goals gt                           lt goal gt shade lt  goal gt                       lt  goals gt                       lt configuration gt                           lt artifactSet gt                           lt  -- signed jars-- gt                               lt excludes gt                                   lt exclude gt bouncycastle bcprov-jdk15 lt  exclude gt                               lt  excludes gt                           lt  artifactSet gt                             lt transformers gt                               lt transformer                                 implementation  org apache maven plugins shade resource ManifestResourceTransformer  gt                                   lt  -- Main class -- gt                                   lt mainClass gt com main MyMainClass lt  mainClass gt                               lt  transformer gt                               lt  -- Use resource transformers to prevent file overwrites -- gt                               lt transformer                                   implementation  org apache maven plugins shade resource AppendingTransformer  gt                                   lt resource gt properties properties lt  resource gt                               lt  transformer gt                               lt transformer                                 implementation  org apache maven plugins shade resource XmlAppendingTransformer  gt                                   lt resource gt applicationContext xml lt  resource gt                               lt  transformer gt                               lt transformer                                 implementation  org apache maven plugins shade resource AppendingTransformer  gt                                   lt resource gt META-INF cxf cxf extension lt  resource gt                               lt  transformer gt                               lt transformer                                 implementation  org apache maven plugins shade resource XmlAppendingTransformer  gt                                   lt resource gt META-INF cxf bus-extensions xml lt  resource gt                               lt  transformer gt                        lt  transformers gt                       lt  configuration gt                   lt  execution gt               lt  executions gt           lt  plugin gt        lt  plugins gt

Another option if you really want to repackage the other JARs contents inside your single resultant JAR is the Maven Assembly plugin   It unpacks and then repacks everything into a directory via  lt unpack gt true lt  unpack gt   Then you d have a second pass that built it into one massive JAR   Another option is the OneJar plugin   This performs the above repackaging actions all in one step
