http://fiji.sc/Uber-JAR提供了一个很好的解释:

There are three common methods for constructing an uber-JAR: Unshaded. Unpack all JAR files, then repack them into a single JAR. Pro: Works with Java's default class loader. Con: Files present in multiple JAR files with the same path (e.g., META-INF/services/javax.script.ScriptEngineFactory) will overwrite one another, resulting in faulty behavior. Tools: Maven Assembly Plugin, Classworlds Uberjar Shaded. Same as unshaded, but rename (i.e., "shade") all packages of all dependencies. Pro: Works with Java's default class loader. Avoids some (not all) dependency version clashes. Con: Files present in multiple JAR files with the same path (e.g., META-INF/services/javax.script.ScriptEngineFactory) will overwrite one another, resulting in faulty behavior. Tools: Maven Shade Plugin JAR of JARs. The final JAR file contains the other JAR files embedded within. Pro: Avoids dependency version clashes. All resource files are preserved. Con: Needs to bundle a special "bootstrap" classloader to enable Java to load classes from the wrapped JAR files. Debugging class loader issues becomes more complex. Tools: Eclipse JAR File Exporter, One-JAR.

我试图做一些类似的事情，但我不希望所有的罐子都包括在内。我想从给定的依赖项中包含一些特定的目录。另外，分类器标签已经被占用，所以我不能做:

<dependencies>
    <dependency>
        <groupId>your.group.id</groupId>
        <artifactId>your.artifact.id</artifactId>
        <version>1.0</version>
        <type>jar</type>
        <classifier>jar-with-dependencies</classifier>
    </dependency>
</dependencies>

我使用maven-dependency-plugin和unpack goal 并将我想要的内容解压缩到${project.build。目录}/类，否则将省略 因为它在classes目录中，maven最终将它放在jar中

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>unpack</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>unpack</goal>
            </goals>
            <configuration>
                <artifactItems>
                    <artifactItem>
                        <groupId>my.group</groupId>
                        <artifactId>my.artifact</artifactId>
                        <classifier>occupied</classifier>
                        <version>1.0</version>
                        <type>jar</type>
                    </artifactItem>
                </artifactItems>
                <outputDirectory>${project.build.directory}/classes</outputDirectory>
                <includes>aaa/**, bbb/**, ccc/**</includes>
            </configuration>
        </execution>
    </executions>
</plugin>

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>
                </goals>
            </execution>
        </executions>
        <configuration>
            <descriptorRefs>
                <descriptorRef>dependencies</descriptorRef>
            </descriptorRefs>
        </configuration>
    </plugin>
</plugins>

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)。

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。

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
