> maven-war-plugin copies jar files of dependent artifacts to WEB-INF/lib
> directory. with filename as is. It could make trouble when the version of
> depenedent artifact is snapshot.
> If the artifact was downloaded from remote repository, the jar filename in
> local repository contains timestamp value. (eg.
> deplib-1.0.0-20121220.074535-93.jar )
> If the artifact was built in workspace, the jar file in local repository
> contains 'SNAPSHOT'. (eg. deplib-1.0.0-SNAPSHOT.jar )
> Guess multimodule project MyProject which has submodules modA and modWAR,
> where modWAR is dependent to modA.
> MyProject |-- modA
> |-- modWAR
> When I built just modWAR in my PC, maven (maybe war plugin) looks for
> repository, and then find modA-0.1-20130101.074535-93.jar, copy this file to
> WEB-INF/lib with same filename.
> Then, I 'mvn install' upper moudule MyProject, the submodules will be built.
> modA is built and copied to local repository with filename
> modA-0.1-SNAPSHOT.jar, and war plugin will copy modA-0.1-SNAPSHOT.jar to
> WEB-INF/lib when submodule modWAR is built. Now, there are two modA jar files
> in WEB-INF/lib directory of modWAR; modA-0.1-20130101.074535-93.jar and
> modA-0.1-SNAPSHOT.jar.
> If co-work developer build modA and deploy next day in his PC, the lastest
> snapshot file will look like modA-0.1-20130102.110000-1.jar
> I build modWAR without cleaning modWAR beforehand. maven will find newer
> snapshot of modA, download it, and copy it to WEB-INF/lib without deleting
> older snapshot version. There are three of modA jar files now.
> This behavier is different from that of dependey-plugin. 'mvn
> dependency:copy-dependencies' will copy files to target directory, changing
> timestamp value of filename to 'SNAPSHOT'. There is duplicated dependent
> library problem.
> I think maven-war-plugin's copying behavier should be like dependent-plugin.
