java - 如何让 ProGuard Maven 插件使用最新的 ProGuard 版本？

Question

我有一个 pom.xml 文件如下。当我运行 mvn clean install 时，出现错误

[proguard] Error: Can't read [C:\Program Files\Java\jdk1.8.0_20\jre\lib\rt.jar] 
(Can't process class [com/oracle/net/Sdp$1.class] (Unsupported class version number 
[52.0] (maximum 51.0, Java 1.7)))

我尝试升级ProGuard版本，在pom.xml文件中设置为5.2

但是当我运行 mvn clean install 时，我在控制台中收到以下消息:

[INFO] proguard jar: C:\Users\DP118M\.m2\repository\net\sf\proguard\proguard-base\4.11\proguard-base-4.11.jar
 [proguard] ProGuard, version 4.11

如何让 Maven ProGuard 插件使用 ProGuard 版本 5.2 而不是 4.11？

这是完整的 pom.xml:

Answer 1

我通过将 proguard-maven-plugin 的版本从 2.0.7 更改为 2.0.8 解决了这个问题。
