大约1个月前，我仍然可以运行TeamCity服务器，但到目前为止，它说找不到1.8版本的Java可执行文件。
我已经设置了环境变量：
JAVA_HOME=C:\Program Files\JAVA\jdk-11.0.1
JRE_HOME=C:\Program Files\Java\jre1.8.0_192
CATALINA_HOME=C:\apache-toncat-9.0.12
在Path变量中，我已将其设置为：
%JAVA_HOME%\bin；%JRE_HOME%\bin；%目录_主页%\lib
但它仍然表示找不到JAVA_HOME或JRE_HOME。
我在下面附上了TeamCity服务器日志。

我在阅读了这个答案后找到了我的解决方案'；…的原因是什么'；未被识别为内部或外部命令、可操作程序或批处理文件。基本上TeamCity只得到JRE_HOME变量，而没有Path变量，所以里面没有..bin。我只是在设置TeamCity时编辑JRE_HOME，它就工作了。
我也遇到过类似的问题，可以通过以下操作解决：
- 下载TeamCity的.exe安装程序
- 将其安装到新文件夹中
- 从新的安装文件夹中复制"jre"文件夹，并将其粘贴到原始TeamCity安装文件夹中
我也遇到了这个问题。事实证明，答案是调试日志中早些时候的"findstr"错误。由于某种原因，我的Windows生成服务器在其PATH上丢失了"C:\Windows\System32"团队城市内部批处理文件使用Findstr来解析Java的版本。这会导致启动脚本后退，并假定没有安装Java。一旦我将这个目录添加回路径中，服务器就会正常启动。
