Maven How to include jars which are not available in reps into a J2EE project

Question

in my J2EE project I ve a couple of dependencies  which are not available in any Maven repository  because they re proprietary libraries  These libraries need to be available at runtime  so that have to be copied to target     WEB-INF lib      Right now  I m listing them as system dependency in my POM  but with this method the problem is  that aren t being copied to the target build during compilation  Also this method is not very elegant   So which is the best way to integrate them in Maven   Note  I don t want to create my own Maven repository

For people wanting a quick solution to this problem:

<dependency>
  <groupId>LIB_NAME</groupId>
  <artifactId>LIB_NAME</artifactId>
  <version>1.0.0</version>
  <scope>system</scope>
  <systemPath>${basedir}/WebContent/WEB-INF/lib/YOUR_LIB.jar</systemPath>
</dependency>

just give your library a unique groupID and artifact name and point to where it is in the file system. You are good to go.

Of course this is a dirty quick fix that will ONLY work on your machine and if you don't change the path to the libs. But some times, that's all you want, to run and do a few tests.

EDIT: just re-red the question and realised the user was already using my solution as a temporary fix. I'll leave my answer as a quick help for others that come to this question. If anyone disagrees with this please leave me a comment. :)

If I am understanding well  if what you want to do is to export dependencies during the compilation phase so there will be no need to retrieve manually each needed libraries  you can use the mojo copy-dependencies   Hope it can be useful in your case  examples

Ric Jafe s solution is what worked for me   This is exactly what I was looking for  A way to push it through for research test code  Nothing fancy  Yeah I know that that s what they all say    The various maven plugin solutions seem to be overkill for my purposes  I have some jars that were given to me as 3rd party libs with a pom file  I want it to compile run quickly  This solution which I trivially adapted to python worked wonders for me  Cut and pasted into my pom   Python Perl code for this task is in this Q amp A  Can I add jars to maven 2 build classpath without installing them   def AddJars jarList     s1        for elem in jarList     s1             lt dependency gt           lt groupId gt local dummy lt  groupId gt           lt artifactId gt  s lt  artifactId gt           lt version gt 0 0 1 lt  version gt           lt scope gt system lt  scope gt           lt systemPath gt   project basedir  manual jars  s lt  systemPath gt        lt  dependency gt  n     elem  elem    return s1

As you ve said you don t want to set up your own repository  perhaps this will help   You can use the install-file goal of the maven-install-plugin to install a file to the local repository  If you create a script with a Maven invocation for each file and keep it alongside the jars  you  and anyone else with access  can easily install the jars  and associated pom files  to their local repository   For example   mvn install install-file -Dfile  usr jars foo jar -DpomFile  usr jars foo pom mvn install install-file -Dfile  usr jars bar jar -DpomFile  usr jars bar pom   or just   mvn install install-file -Dfile ojdbc14 jar -DgroupId com oracle -DartifactId ojdbc14 -Dversion 10 2 0 -Dpackaging jar   You can then reference the dependencies as normal in your project   However your best bet is still to set up an internal remote repository and I d recommend using Nexus myself  It can run on your development box if needed  and the overhead is minimal

Create a repository folder under your project  Let s take    project basedir  src main resources repo   Then  install your custom jar to this repo   mvn install install-file -Dfile  FILE PATH    -DgroupId  GROUP  -DartifactId  ARTIFACT  -Dversion  VERS     -Dpackaging jar -DlocalRepositoryPath  REPO DIR    Lastly  add the following repo and dependency definitions to the projects pom xml    lt repositories gt       lt repository gt           lt id gt project-repo lt  id gt           lt url gt file     project basedir  src main resources repo lt  url gt       lt  repository gt   lt  repositories gt    lt dependencies gt           lt dependency gt           lt groupId gt  GROUP  lt  groupId gt           lt artifactId gt  ARTIFACT  lt  artifactId gt           lt version gt  VERS  lt  version gt       lt  dependency gt   lt  dependencies gt

None of the solutions work if you are using Jenkins build   When pom is run inside Jenkins build server   these solutions will fail  as Jenkins run pom will try to download these files from enterprise repository   Copy jars under src main resources lib  create lib folder   These will be part of your project and go all the way to deployment server  In deployment server  make sure your startup scripts contain src main resources lib   in classpath  Viola

Install alone didn t work for me    mvn deploy deploy-file -Durl file    home me project lib      -Dfile target jzmq-2 1 3-SNAPSHOT jar -DgroupId org zeromq       -DartifactId zeromq -Dpackaging jar -Dversion 2 1 3

You need to set up a local repository that will host such libraries  There are a number of projects that do exactly that  For example Artifactory

Continue to use them as a system dependency and copy them over to target     WEB-INF lib     using the Maven dependency plugin   http   maven apache org plugins maven-dependency-plugin examples copying-artifacts html
