如何为maven项目生成混淆后的jar文件

Question

我正在使用 Eclipse IDE 和 java 7 java 中的 maven 架构项目开发 java 应用程序

我需要生成一个混淆的 jar 文件，其中还必须包含所有混淆的依赖项我一直在检查一些解决方案，但我一直无法获得所需的结果。

我查过的一些地方是这样的：

Lin1,Link2, Link3

来自我当前大部分实现的前两个链接

这是我的 pom.xml 文件：

我得到的错误如下：

[ERROR] Failed to execute goal com.pyx4me:proguard-maven-plugin:2.0.4:proguard (default) on project CacheClienteModelC: Can't rename E:\Users\B267481\Documents\ServidorDesarroCreditoAcertum\CacheClienteModelC\target\CacheClienteModelC.jar -> [Help 1]

只是为了让事情更清楚当我构建项目时，在目标文件夹中生成了两个不同的 jar（CacheClienteModelC-jar-with-dependecies.jar 和 CacheClienteModelC.jar），我尝试生成的文件是 CacheClienteModelC-small.jar （混淆的 jar）从未创建过。

我应该如何配置插件来混淆我的项目文件？

Answer 1

您使用的是旧版本的 Maven proguard 插件，您应该使用 this 一个，您可以在 Maven 中央存储库中找到它。

现在至于你的 pom.xml，从依赖中删除 com.pyx4me 依赖，你在那里不需要它。

现在关于插件配置尝试这样的东西：

<plugin>
    <groupId>com.github.wvengen</groupId>
    <artifactId>proguard-maven-plugin</artifactId>
    <version>2.0.10</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>proguard</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <obfuscate>true</obfuscate>
        <injar>${project.build.finalName}.jar</injar>
        <outjar>${project.build.finalName}-small.jar</outjar>
        <includeDependency>true</includeDependency>
        <options>
            <option>-keep public class your.package.Main { *; }</option>
        </options>
        <libs>
            <lib>${java.home}/lib/rt.jar</lib>
            <lib>${java.home}/lib/jce.jar</lib>
        </libs>
        <archive>
            <manifest>
                <mainClass>Main</mainClass>
                <packageName>your.package</packageName>
            </manifest>
        </archive>

    </configuration>
    <dependencies>

        <dependency>
            <groupId>net.sf.proguard</groupId>
            <artifactId>proguard-base</artifactId>
            <version>4.10</version>
            <scope>runtime</scope>
        </dependency>

    </dependencies>
</plugin>

看看你是怎么在里面指定proguard的依赖的？那应该毫无问题地生成混淆的 jar。试试吧。
