gradle - Gradle String索引超出范围:0

Question

我正在记录我在这里遇到的问题，因为在寻找解决方案之前，我一直在寻找解决方案。我希望它也可以帮助其他人...

我遇到的问题是，每当我用Gradle 2.14.x执行任何gradle任务时，我都会收到String index out of range: 0异常。 Gradle 2.12.x一切正常。

调试输出也不是很有用:

$ gradle compileJava --debug

我从互联网上的不同文章中读到的那是由于我的属性文件中的语法错误。但是，即使完全清空了那些文件，我也无法让Gradle运行。

该问题实际上确实发生在我的一个属性文件中:~/.gradle/gradle.properties包含字符串:::properties，该字符串是我从文档中复制并错误粘贴的。
