Maven：将第三方jar的导出jar添加到manifest中的classpath [英] Maven: Export jar with 3rd-party jars added to classpath in manifest

问题描述

我正在使用Eclipse 开发 Java maven项目，并希望导出包含所有引用库的jar 。这些引用的库属于以下两个类别之一：

I am developing a Java maven project with Eclipse and want to export a jar that includes all referenced libraries. These referenced libraries fall into one of these two categories:

1. 它们是显式（或隐式） 依赖于 pom.xml

1. They are explicit (or implicit) dependencies in the pom.xml

我有一些库不能作为maven工件并将它们放在/ lib中（并将它们添加到Eclipse中的构建路径中）

I have some libraries not available as maven artifacts and have put them in /lib (and added them to the build path in Eclipse)

有 maven-assembly-plugin ，适用于1）。但是，我无法找到包含非maven依赖关系的maven插件，例如/ lib中的所有jar。

There's the maven-assembly-plugin, which works fine for 1). However, I'm unable to find a maven plugin that also includes non-maven-dependencies, e.g. "all jars in /lib".

然后是Eclipse FatJar 插件，哪种工作，但自2009年以来一直没有更新，所以它似乎没有维护。另外我更喜欢我可以在 pom.xml 中直接指定的导出方法。

Then there's the Eclipse FatJar plugin, which sort of works, but hasn't been updated since 2009, so it seems unmaintained. Also I prefer an export method that I can directly specify in the pom.xml.

任何人都可以指向我导出所有引用的库的 maven 插件等，包括案例2中的那些？）？这只需要将它们放在jar中并在manifest的类路径中引用它们。

Can anyone point me to a maven plugin or the like to export all referenced libraries, including those from case 2) ? That only needs to involve putting them in the jar and referencing them in the manifest's classpath.

谢谢！

推荐答案

我认为处理此问题的最佳方法是将自定义库包含到本地maven存储库中。现在您可以将库作为maven依赖项包含在内，并且可以使用maven-assembly-plugin导出pom中指定的所有依赖项。

I think the best way to handle this is to include your custom libs into a local maven repository. Now you can inlcude your libraries as maven dependencies and you can export all your dependencies specified in your pom with the maven-assembly-plugin.

Here is a tutorial, how to put your libs into a local repository in maven to use it in your pom. http://www.mkyong.com/maven/how-to-include-library-manully-into-maven-local-repository/

在你的pom.xml中：

And in your pom.xml:

<!-- setup jar manifest to executable with dependencies -->
<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
    <descriptorRefs>
      <descriptorRef>jar-with-dependencies</descriptorRef>
    </descriptorRefs>
    <archive>
      <manifest>
        <mainClass>your.main.class</mainClass>
      </manifest>
    </archive>
  </configuration>
  <executions>
    <execution>
      <phase>package</phase>
      <goals>
       <goal>single</goal>
      </goals>  
    </execution>
  </executions>
</plugin>
