如何使用maven创建一个可运行的jar,其中包含一个单独的"lib"文件夹(不是超级jar)中的依赖项

Question

我正在尝试使用Maven创建一个可执行jar文件,其中包含单独目录中的依赖项.我已经看到很多关于创造"uberjar"的问题 - 我不希望如此.我想要的是将依赖项复制到像这样的"lib"目录中(以及MANIFEST.MF带有ClassPath指向它们的条目的jar 文件):

/myApp
  myApp.SNAPSHOT-1.0.jar
  /lib
    hibernate.jar
    log4j.jar
    ...

作为一个额外的奖励,如果我可以复制/src/main/resources/*到/myApp/conf然后压缩整个/myApp目录,那将myApp.zip是很好的.

编辑:我使用maven-dependency-plugin和maven-resources-plugin以及maven-jar-plugin.这是我在我的pom.xml中包含的内容(它将运行时依赖项复制到/ target/release/lib,以便我可以压缩/目标/发布并准备好了):

maven依赖插件有一个复制依赖目标,可以做你想要的.

mvn dependency:copy-dependencies

请参阅此处了解可用选项.即'outputDirectory'将依赖项复制到/ lib
