问题 ProGuard不会使JAR与依赖项混淆

我有一个项目 pom.xml 文件如下。当我发出命令 mvn clean compile assembly:single install 我希望Maven生成一个包含的JAR

所有的依赖和
我的代码的混淆版本。

它不起作用 - 我的代码在“jar-with-dependencies”文件中没有被混淆。

当我跑 mvn clean compile install 生成的文件包含我的应用程序的模糊代码，但没有依赖项。

为了拥有包含所有依赖项和混淆代码的JAR文件，我该怎么办？

起源

答案:

proguard-maven-plugin 将模糊项目的主要工件，而不是辅助工件 jar-with-dependencies 那个 maven-assembly-plugin 产生。

您需要配置插件来混淆 jar-with-dependencies 通过指定 injar 属性：

指定要处理的应用程序的输入jar名称（或战争，耳朵，拉链）。

<injar>${project.build.finalName}-jar-with-dependencies.jar</injar>

现在，在POM中执行插件的顺序也存在问题：我们需要确保 maven-assembly-plugin 在执行之前执行 proguard-maven-plugin。因此，最好定义一个显式执行 maven-assembly-plugin 绑定到 package 相位而不是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，你只需要确保 proguard-maven-plugin 插件配置在你的POM之后。

完成后，调用Maven mvn clean install 将导致带有依赖关系的模糊jar。

为了测试您的实际POM，我添加了两个存储库：

https://repo.spongepowered.org/maven 解决了 spongeapi 依赖。
http://maven.restlet.com 解决了 org.restlet.jse 依赖。

有了这两个依赖项，ProGuard会生成警告，因为 org.restlet.ext.jackson 依赖利用 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，我补充说 -dontwarn 选项，以便在出现警告时ProGuard不会出错。

我能够成功地使用依赖关系模糊jar的最终POM如下：

我遇到了同样的问题，我没有得到你的答案。为什么需要添加存储库？已经在pom中指定了依赖项。为什么Proguard需要更多？此外，您在哪里找到每个依赖项的存储库？你介意看看吗？ stackoverflow.com/questions/36150297/... - Sharcoux

答案:
