我正在开发一个由 .NET 代码和 android java 项目组成的项目。我们试图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 DotCover 生成覆盖率报告，一切看起来都很好。现在，android/java 项目正在使用 ant runners 构建，我们已经为生产和测试项目提供了一些构建脚本，问题似乎是 java 覆盖率报告的创建。
我们创建了一个包含以下 ant 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“在覆盖数据中包含源文件”选项）。
运行构建步骤时发生错误，在日志片段中说明以下内容（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整体统计信息中。
这是日志片段：

有谁知道问题可能是什么？
顺便说一句，当我直接从命令行运行目标时，生成的报告没有任何问题。
问候，每
