我正在做一个由.NET代码和android java项目组成的项目。我们正在努力让这两种类型的项目在一个TeamCity环境中工作。
.NET项目正在通过一些NUnit项目进行测试，我们使用DotCoverr来生成覆盖率报告，一切似乎都很好。现在，android/java项目是使用ant runner构建的，我们有一些用于生产和测试项目的构建脚本，问题似乎是创建java覆盖率报告。
我们创建了一个包含以下蚂蚁目标的构建步骤：
clean emma debug install test
构建步骤设置为启用"Emma coverage runner"（选中选项"Include source files in The coverage data"）。
运行生成步骤时发生错误，在日志片段中声明以下内容（已附加完整的日志文件）。另一个重要问题是android/java单元测试没有出现在构建的总体统计数据中。
这是日志剪辑：

有人知道问题出在哪里吗？
顺便说一句，当我直接从命令行运行目标时，报告的构建没有任何问题。
谨致问候，根据
Android SDK使用的EMMA版本比Sonar EMMA插件使用的版本旧。
代码覆盖率的编码方式似乎在不同版本之间发生了变化，这就是Sonar无法识别格式的原因。
幸运的是，有人想出了一个代码转换器。此处对该问题进行了更详细的描述：http://jira.codehaus.org/browse/SONARPLUGINS-1356
上述代码转换器的java代码也可以从那里下载。
在运行Sonar之前，你只需要对所有.em和.ec文件进行转码，它应该会仔细阅读并测试它们。
