如何使用maven创建一个可运行的jar，该maven包含一个单独的“lib”中的依赖项。文件夹（不是超级罐） [英] How to create a runnable jar with maven that includes dependencies in a separate "lib" folder (not an uber jar)

问题描述

我正在尝试使用Maven创建一个可执行jar文件，该文件包含一个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（以及带有 ClassPath的jar MANIFEST.MF 文件指向他们的条目）：

I'm trying to use Maven to create an executable jar file that includes the dependencies in a separate directory. I've seen a lot of questions on SO about creating an "uberjar"--I don't want that. What I want is to have the depenedencies copied into a "lib" directory like so (and the jar MANIFEST.MF file with a ClassPath entry that points to them):

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

作为一个额外的奖励，如果我可以将 / src / main / resources / * 复制到 / myApp / conf 然后将整个 / myApp 目录压缩到 myApp.zip 中。

As an added bonus it would be nice if I could copy /src/main/resources/* into /myApp/conf and then zip up the entire /myApp directory into myApp.zip as well.

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，这样我就可以压缩/目标/发布并准备好了）：

I use the maven-dependency-plugin and the maven-resources-plugin and the maven-jar-plugin. This is what I include in my pom.xml (which copies the runtime dependencies to /target/release/lib so that I can zip up /target/release and it's ready to go):

推荐答案

maven依赖插件具有复制依赖性目标，应该做你想做的事。

The maven dependency plugin has a copy-dependencies goal that should do what you want.

mvn dependency:copy-dependencies

参见这里可用选项。即'outputDirectory'将依赖项复制到/ lib

See here for the available options. Namely 'outputDirectory' to copy the dependencies to /lib
