我正在尝试将proguard-maven-plugin与proguardVersion 6.0.3一起使用。这是pom.xml中的插件声明：

[proguard] If you don't mind the mentioned classes not being written out,
[proguard] you could try your luck using the '-ignorewarnings' option.

我在做什么错以及如何解决？
答案 0 :(得分：0)
输出日志在一开始就被剪切掉了，所以我看不到哪个软件包引起了这两个警告， 但是如果您使用的是Spring，则可能是log4j引起了问题。
您可以通过添加
进行修复<option>-dontwarn **log4j**,**module-info</option>
