我有一个pom.xml文件，如下所示。当我运行mvn clean install时，我收到错误
[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版本并将其设置为5.2文件中的pom.xml。
但是当我运行mvn clean install时，我会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
如何使Maven ProGuard插件使用ProGuard 5.2版而不是4.11？
这里是完整的pom.xml：

答案 0 :(得分：3)
我通过将proguard-maven-plugin的版本从2.0.7更改为2.0.8来解决了问题。
