有没有办法强制maven(2.0.9)将所有依赖项包含在一个jar文件中?

我有一个项目的构建到一个单一的jar文件。我希望依赖的类也能复制到jar中。

更新:我知道我不能只在jar文件中包含一个jar文件。我正在寻找一种方法来解包指定为依赖项的jar,并将类文件打包到我的jar中。

看看这个答案:

I am creating an installer that runs as a Java JAR file and it needs to unpack WAR and JAR files into appropriate places in the installation directory. The dependency plugin can be used in the package phase with the copy goal and it will download any file in the Maven repository (including WAR files) and write them where ever you need them. I changed the output directory to ${project.build.directory}/classes and then end result is that the normal JAR task includes my files just fine. I can then extract them and write them into the installation directory.

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
    <execution>
        <id>getWar</id>
        <phase>package</phase>
        <goals>
            <goal>copy</goal>
        </goals>
        <configuration>
            <artifactItems>
                <artifactItem>
                    <groupId>the.group.I.use</groupId>
                    <artifactId>MyServerServer</artifactId>
                    <version>${env.JAVA_SERVER_REL_VER}</version>
                    <type>war</type>
                    <destFileName>myWar.war</destFileName>
                </artifactItem>
            </artifactItems>
            <outputDirectory>${project.build.directory}/classes</outputDirectory>
        </configuration>
    </execution>
</executions>

你可以使用带有"jar-with-dependencies"描述符的maven-assembly插件来做到这一点。下面是我们的pom.xml的相关代码块:

  <build>
    <plugins>
      <!-- any other plugins -->
      <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>single</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
        </configuration>
      </plugin>
    </plugins>
  </build>

把Maven放在一边,您可以把JAR库放在Main JAR中,但是您需要使用自己的类加载器。

检查这个项目:One-JAR链接文本

我对月食Luna和m2eclipse的最终解决方案: 自定义类加载器(下载并添加到您的项目,只有5个类) : http://git.eclipse.org/c/jdt/eclipse.jdt.ui.git/plain/org.eclipse.jdt.ui/jar%20in%20jar%20loader/org/eclipse/jdt/internal/jarinjarloader/; 这个类加载器是单jar类加载器中最好的,而且非常快;

< project.mainClass > org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader < / project.mainClass > < project.realMainClass > my.Class < / project.realMainClass >

编辑JIJConstants“Rsrc-Class-Path”为“Class-Path” MVN清洁依赖:复制依赖包 是创建一个jar与依赖lib文件夹与一个瘦类加载器

这是maven插件。它可用于打包和重命名依赖项(以忽略类路径上的依赖项问题)。

谢谢 我已经在POM.xml文件中添加了下面的片段,并解决了Mp问题 创建胖罐子文件,包括所有依赖的罐子。
