proguard-maven-plugin会混淆你的项目，而不是次要神器的主伪影
jar-with-dependencies的
maven-assembly-plugin产生。
您需要
jar-with-dependencies通过指定
injar属性来配置插件以混淆：
指定要处理的应用程序的输入jar名称（或wars，ears，zips）。
<injar>${project.build.finalName}-jar-with-dependencies.jar</injar>现在，在您的POM中，插件的执行顺序也存在问题：我们需要确保在
maven-assembly-plugin之前执行
proguard-maven-plugin。因此，最好为
maven-assembly-plugin绑定到该
package阶段定义一个显式执行，而不是使用从命令行手动调用它
assembly:single。这将是配置：
<plugin> <artifactId>maven-assembly-plugin</artifactId> <executions> <execution> <id>assembly</id> <goals> <goal>single</goal> </goals> <phase>package</phase> <configuration> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> </configuration> </execution> </executions></plugin>
然后，您只需要确保
proguard-maven-plugin插件配置在POM中就可以了。
完成此操作后，使用调用Maven
mvn clean install将导致带有依赖性的混淆jar。
为了测试您的实际POM，我添加了两个存储库：
https://repo.spongepowered.org/maven
解决spongeapi
依赖性。http://maven.restlet.com
解决org.restlet.jse
依赖性。
对于这2个依赖项，ProGuard会生成警告，因为该
org.restlet.ext.jackson依赖项使用
com.sun.msv.*不在构建路径上的类。由于我认为您的代码当前正在工作，这意味着不需要包含这些类，并且可以忽略这些警告。因此，我添加了该
-dontwarn选项，以便在出现警告时ProGuard不会出错。
我能够针对其成功混淆依赖关系的jar的最终POM如下：
