谷歌搜索错误导致很少的结果,我收集的信息的主要部分是Java 8’s static interface methods could cause this,但我还没有找到更多. jar文件我试图遮蔽does indeed have one of these static methods,但即使我仍然必须能够使用它们并遮住罐子？我不确定错误意味着要求“ASM 5”(汇编？),所以任何方向都会受到赞赏.

解决方法
由于我最近遇到了同样的问题,我花了很长时间来修复它,这就是我所做的：
ASM所需的版本是5.0.3.但是,shade插件中当前可用的版本是5.0.2.看看JIRA的门票,它看起来已经在2.4中得到了修复,但是那个版本还没有为公众所用(2015年5月4日到我写这篇文章的时候).
所以你要做的就是通过将这个部分添加到你的pom来激活开发者版本(基于https://maven.apache.org/guides/development/guide-testing-development-plugins.html)：
<pluginRepositories>
<pluginRepository>
<id>apache.snapshots</id>
<url>http://repository.apache.org/snapshots/</url>
</pluginRepository>
</pluginRepositories>
并将插件的版本设置为2.4-SNAPSHOT：
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.4-SNAPSHOT</version>
</plugin>
</plugins>
希望这可以帮助！
