Question

这是我得到的错误：编译错误：javac 未找到类：org.eclipse.jdt.core.JDTCompilerAdapter

我正在尝试使用ant构建步骤运行构建配置并继续收到此错误。据我所知，我已经正确设置了环境变量，我认为TeamCity带有编译.java文件所需的一切，为什么找不到javac.exe？

告诉我可以提供的详细信息。可以在此处找到存储库：https://code.google.com/p/ci-research-teamcity-test-project/source/browse

错误发生在build.xml脚本中我正在使用Eclipse提供的生成的build.xml：

这是我的build_custom.xml，它可以工作，它被修剪和简化：
（注意javac任务中的编译器=＆＃34;现代＆＃34;属性，这修复了我得到的另一个错误，即编译错误：javac - 找不到类：javac1.8）

TeamCity无法找到javac，尝试使用ant构建步骤运行构建配置
