!! Eclipse integration

I installed the Eclipse QE plugin by adding [http://q4e.googlecode.com/svn/trunk/updatesite-iam/] to the list of software sites and check the Core features plus the Eclipse IAM editor

__Create maven project__

By hand it can be done with :
%%small
{{{
mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
}}}
%%

Of use Eclipse New Project....



!! Dependencies

I have a dependency on x.y.z., how do I know the artifactid, groupID and version of it ?\\
A very brute way would be to search for pom files in the repository :
{{{
metskem@gneisenau:~$ find .m2/repository/ -name *.pom|wc
    384     384   32808
}}}
In a pom file you will find what you need :
%%prettify
{{{
<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>commons-lang</groupId>
  <artifactId>commons-lang</artifactId>
  <name>Lang</name>
  <version>2.1</version>
  <description>Commons.Lang, a package of Java utility classes for the
    classes that are in java.lang's hierarchy, or are considered to be so
    standard as to justify existence in java.lang.</description>
  <url>http://jakarta.apache.org/commons/${pom.artifactId.substring(8)}/</url>

! Create repository entry

I have a project that requires WebSphere jars for compile, how do I arrange that with maven dependencies, I could not find a dependency for that (of course).\\
You can make it yourself with the install plugin :
%%small
{{{
metskem@gneisenau:~$ mvn install:install-file -Dfile=/home/metskem/java_libs/com.ibm.ws.admin.client_7.0.0.jar -DgroupId=com.ibm.websphere -DartifactId=admin.client -Dversion=7.0.0 -Dpackaging=jar -DgeneratePom=true
