Maven 打包可运行 jar
为配合自动化部署hudson,最近研究了如何将eclipse maven工程打包成可运行的jar函数及对应的资源文件。
由于我们工程中包含了多个可运行的任务,在打包成jar时需要分别导出,pom提到版本库需要一致,不能部署一个任务提交一次代码。所以考虑了在进行mvn打包时通过传递参数控制导出jar中的main所在的类。在pom中定义properties,在执行命令时传递参数即可。如mvn package -DtaskFinalName=contentpoolurl -DmainClassName=com.ifec.blueair.task.contentpoolurl.ContentPoolUrlRun,另外在通过mvn导出jar找不到配置文件,发现没有找到当前目录,通过加入manifestEntries即可指定目录。maven生成的MANIFEST.MF中的Class-Path的内容缺少一些内容,比如当前执行目录(.),那么可以通过上面manifestEntries的方式增加进来。
pom.xml内容如下:
