Question

我正在使用命令 ant clean debug emma install test 从命令行使用Apache Ant构建我的Android项目，一切运行正常（测试工作和构建成功）。虽然Jenkins构建的相同命令（ANT，JAVA，ANDROID_SDK已配置）在最后的构建步骤中引发错误：

Jenkins托管在我的本地机器上（从命令行完美地构建了这个项目），我很困惑，为什么会出现这个错误。使用emma.jar看起来很麻烦，但我无法找到，如何修复Jenkins中的建筑项目。

有什么想法吗？

找到解决方案。我们必须执行命令（字的顺序非常重要）：

ant clean emma debug install test

并从我们的类路径（libs文件夹）中排除任何emma库。一切都很简单。

使用Jenkins构建Android项目会抛出com.android.dex.DexException，而命令行构建可能会起作用
