我尝试在ANT下运行Activiti BPM工具，但得到以下错误：-错误：-“java”未被识别为内部或外部命令；当我尝试在windows 7下使用CMD命令行启动演示应用程序时，我得到了以下错误：-

有谁知道出了什么问题？断续器

Answer 1

我有类似的问题。由于某种原因，Java JDK已正确安装在C：\程序文件（x86）\Java上，但在路径中它被设置为C：\程序文件\Java...一旦我纠正了路径变量，它就解决了这个问题。

此外，如果您有Jenkins和Java使用相同的端口号，这可能会导致一切正常的外观，您需要让它们使用单独的端口号。要检查此停止Jenkins它是否作为服务运行，然后重新启动Tomcat

Answer 2

只需将C:\ProgramFiles\Java\jdk1.7.0_06\bin添加到路径中。

原因是批处理文件 C：\激活-5.10\活动-5.10\应用程序\h2\h2.start.bat具有一个原始 java 命令，该命令依赖于 java.exe位于 PATH 上。

Answer 3

错误：- “java”未被识别为内部或外部命令;

这意味着＜code＞java。exe不是路径的一部分
将%JAVA_HOME%\bin添加到路径
