Hayarobi Park created MWAR-296: ---------------------------------- Summary: maven-war-plugin can cause multiple dependent lib files with same snapshot version. Key: MWAR-296 URL: https://jira.codehaus.org/browse/MWAR-296 Project: Maven 2.x WAR Plugin Issue Type: Bug Affects Versions: 2.3 Reporter: Hayarobi Park
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. -- This message is automatically generated by JIRA.
