Maven运行任何命令都报错“Internal error: java.lang.ArrayIndexOutOfBoundsException”

今天遇到一个奇怪的问题，在maven工程下运行任何mvn命令都报“Internal error: java.lang.ArrayIndexOutOfBoundsException”错误，具体错误如下：

$ mvn install

1. 网上有人说说是pom.xml文件错误，第一行缺少下面行，但是加上后问题依旧。

<?xml version="1.0" encoding="UTF-8" ?>

2. 还有说是 ～/.m2/settings.xml 文件有错误，我干脆把这个文件删除了，问题还在。

3. 最后抱着试试看的心态升级了一下maven版本，从原先3.3.3升级到3.8.8，问题解决了，但是具体原因还是不明。
