How do I add a Maven dependency in Eclipse

Question

I don t know how to use Maven at all   I ve been developing for a couple years with Eclipse and haven t yet needed to know about it   However  now I m looking at some docs that suggest I do the following     To include it within your project  just add this maven dependency to your build     lt repository gt      lt id gt jboss lt  id gt      lt url gt http   repository jboss org maven2 lt  url gt   lt  repository gt           lt dependency gt      lt groupId gt org jboss resteasy lt  groupId gt      lt artifactId gt resteasy-jackson-provider lt  artifactId gt      lt version gt 1 1 GA lt  version gt   lt  dependency gt    How do I do this with my Eclipse project    Please assume I know nothing about Maven  I just figured out it might be installed on my computer by typing mvn on the command line  but that s seriously the extent of my knowledge   I would be happy to continue knowing nothing about Maven if there is an equivalent  non-Maven way of following these instructions with Eclipse

On the top menu bar  open Window - gt  Show View - gt  Other In the Show View window  open Maven - gt  Maven Repositories    In the window that appears  right-click on Global Repositories and select Go Into Right-click on  quot central  http   repo maven apache org maven2  quot  and select  quot Rebuild Index quot    Note that it will take very long to complete the download      Once indexing is complete  Right-click on the project - gt  Maven - gt  Add Dependency and start typing the name of the project you want to import  such as  quot hibernate quot      The search results will auto-fill in the  quot Search Results quot  box below

You need to be using a Maven plugin for Eclipse in order to do this properly  The m2e plugin is built into the latest version of Eclipse  and does a decent if not perfect job of integrating Maven into the IDE  You will want to create your project as a  Maven Project   Alternatively you can import an existing Maven POM into your workspace to automatically create projects  Once you have your Maven project in the IDE  simply open up the POM and add your dependency to it   Now  if you do not have a Maven plugin for Eclipse  you will need to get the jar s  for the dependency in question and manually add them as classpath references to your project  This could get unpleasant as you will need not just the top level JAR  but all its dependencies as well   Basically  I recommend you get a decent Maven plugin for Eclipse and let it handle the dependency management for you

Open the pom xml file   under the project tag add  lt dependencies gt  as another tag  and google for the Maven dependencies  I used this to search    So after getting the dependency create another tag dependency inside  lt dependencies gt  tag   So ultimately it will look something like this    lt project xmlns  http   maven apache org POM 4 0 0  xmlns xsi  http   www w3 org 2001 XMLSchema-instance  xsi schemaLocation  http   maven apache org POM 4 0 0 http   maven apache org xsd maven-4 0 0 xsd  gt     lt modelVersion gt 4 0 0 lt  modelVersion gt     lt groupId gt doc-examples lt  groupId gt     lt artifactId gt lambda-java-example lt  artifactId gt     lt version gt 0 0 1-SNAPSHOT lt  version gt     lt name gt lambda-java-example lt  name gt     lt dependencies gt         lt  -- https   mvnrepository com artifact com amazonaws aws-lambda-java-core -- gt       lt dependency gt           lt groupId gt com amazonaws lt  groupId gt           lt artifactId gt aws-lambda-java-core lt  artifactId gt           lt version gt 1 0 0 lt  version gt       lt  dependency gt     lt  dependencies gt   lt  project gt    Hope it helps

I have faced the similar issue and fixed by copying the missing Jar files in to  M2 Path   For example  if you see the error message as Missing artifact tws axis-client jar 8 7 then you have to download  axis-client-8 7 jar  file and paste the same in to below location will resolve the issue   C  Users UsernameXXX m2 repository tws axis-client 8 7 Paste axis-client-8 7 jar    finally  right click on project- Maven- Update Project   Thats it   happy coding
