I just found a fix, I hope it helps you.

The fix did not help me. I seems a somewhat of a workaround too. I opened the jar in two different zip toos and jar -tvf. In jar and winrar the pom.xml and pom.proerties are listed twice!!. In winexpress only once. The gradle exception says java.util.zip.ZipException so something is wrong here. In jar tvf the files are listed once during the listing of folders an once again at the end of the listing - as files. I guess gradle must handle java listings from java.util.zip / jar and not throw exception. I will try to file a more official bug report with the android community.

我也碰到了类似问题，使用 Java8 就没有问题了

把pinyin4j升级到2.5.1就好了

把pinyin4j升级到2.5.1就好了

但是我看pinyin4j这个仓库最新的版本就仅仅只到2.5.0，2.5.1已经发布了吗？

嗯嗯，升级到2.5.1后确实就可以了

有人知道出现这个问题最根本的原因是什么吗？
