Question

尝试使用Gradle编译Android项目并得到一个奇怪的错误。当我运行./gradlew tasks --stacktrace时。尝试干净的重建，回购的新鲜克隆，不同的分支，同事们能够建立aok。

寻找要检查/尝试解决此问题的想法。

*更新：恢复为Gradle 2.11，com.android.tools.build:gradle:2.2.0-alpha6似乎解决了这个问题。 *

这是堆栈：

FAILURE: Build failed with an exception.

* What went wrong:
String index out of range: 0

* Try:
Run with --info or --debug option to get more log output.

* Exception is:
java.lang.StringIndexOutOfBoundsException: String index out of range: 0

Answer 1

合并冲突对我造成了这一影响。冲突发生在gradle.properties中。我认为是<<<<<<< HEAD之类的行。如果该消息更具描述性，那将很有帮助。

Answer 2

=是一个键值分隔符。如果要在属性文件中拆分部分，可以使用注释：

foo.bar=foo
#=======
foo.baz=baz

更多信息可在以下网址找到：properties file format。

Answer 3

我通过删除全局gradle.properties文件~/.gradle/gradle.properties中的所有条目找到了该问题

因此，我的上一个文件中必定存在gradle不喜欢的内容。复制并粘贴几个部分后，我发现这是罪魁祸首

=======

我一直在使用======来拆分我的gradle属性的部分（我已经定义了开源和商业键/属性）。

在gradle 2.11的早期版本中，这是aok并且编译得很好但是在2.14.1上你得到了神秘的错误“String index out of range：0”。

Answer 4

对我来说，问题是由于gradle.properties的SVN冲突造成的，如下所示： bin build.gradle gradle.properties gradle.properties.r91662 src build build.num gradle.properties.mine gradle.properties.r91979 tmp

有一次，我把gradle.properties作为svn解决，gradle build开始正常工作。

Answer 5

这表示gradle.properties中存在一些错误的值，请删除无效的enteries。

Answer 6

删除为我工作的~/.gradle/目录，当我将我的android工作室更新为Exception:String index out of range:0

时，Gradle 2.3.1

Answer 7

检查您的findMyEl(String prefix, int maxEls)，如果项目中包含已移除/不存在模块。

我在settings.gradle文件中仍然已经删除模块谎言</ strong>。删除它解决了我的问题。

Answer 8

检查你的文件，它可能是你有一个未解决的合并冲突，它在你的代码中添加了不需要的额外字符，比如 <===== head 或其他 git 语法在 github vscode 扩展的帮助下将有助于减少立即搜索并将您指向外国不需要的字符

删除 ~/.gradle/ 目录
