在Maven的jar中包含依赖项

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。

如果你想做一个可执行的jar文件，他们也需要设置主类。所以全构型应该是。

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。

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>single</goal>

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

方法1:将依赖的JAR文件复制到target/lib中，然后将它们添加到MANIFEST中的JAR类路径中:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <configuration>
                <outputDirectory>${project.build.directory}/lib</outputDirectory>
                <excludeTransitive>false</excludeTransitive> 
                <stripVersion>false</stripVersion>
            </configuration>
            <executions>
                <execution>
                    <id>copy-dependencies</id>
                    <phase>package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        <!-- Add LIB folder to classPath -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <archive>
                    <manifest>
                        <addClasspath>true</addClasspath>
                        <classpathPrefix>lib/</classpathPrefix>
                    </manifest>
                </archive>
            </configuration>
        </plugin>

方法2:解包所有依赖项，并将它们的类和资源重新打包到一个平面JAR中。注意:重叠的资源会随机丢失!

<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>

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>

我发现这是最明确的答案;这里的其他答案是缺少一些对我来说不明显的东西，例如MVN清洁包命令，以及单独添加插件作为依赖项。所有这些对于更习惯的专业用户来说可能是显而易见的。
