输出一下详细到Gradle编译的详细Info.查看是不是因为NuwaGradle这个编译项目里面NuwaPlugin.groovy或则是util/NuwaProcessor.groovy这个两个类报的数组越界错误。女娲坑太多，这只是一个Demo,不要运用在实际项目中。

@DoubleAngle 最终定位的原因是mapping文件没找到，不知道怎么回事 Caused by: java.io.FileNotFoundException: Source '/Users/.../build/outputs/mapping/release/mapping.txt' does not exist

[WPCWEG]

mapping是你在编译过程中就会生成的
