对于我的两个Android项目，我在构建过程中收到错误消息：
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:mergeDebugResources'.
> java.lang.NoClassDefFoundError: Could not initialize class sun.dc.pr.Rasterizer
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
进一步使用--stacktrace我得到以下日志输出：

当我删除所有矢量绘图并用任何其他* .png图像替换它时，它可以工作，错误消失了。 向量的问题是什么？之前有效，为什么它还有效？
