当导致 makefile 更改目录并且 运行 ant 在那个新目录错误 "JAVA_HOME is not defined correctly"
When causing a makefile to change directory and run ant in that new directory error "JAVA_HOME is not defined correctly"
即使您通过 windows 安装程序安装了 Java and/or ant，您仍然需要 set your environment variables。确保将 java 链接到 JDK 而不是 JRE，我作为新手的猜测是，当您编译自己的代码时，您应该始终使用 JDK您需要的所有工具。

这一切都发生在 Windows。我叫作。它从 svn 检出一个 "code" 文件夹到 makefile 所在的目录中。在 "code" 里面是一个 build.xml。我希望我的 makefile 更改为该目录，然后 运行 ant 就可以了。我在命令提示符中收到错误消息：

我在这里查看 http://sunsite.ualberta.ca/Documentation/Gnu/make-3.79/html_chapter/make_5.html#SEC46 似乎这应该可以在我的 makefile 中实现：
runant:
cd code; ant clean compile jar run
因为这将在子 shell 中打开命令，但它也会 运行 在该子 shell 中运行。
如果我手动切换到代码文件夹和 运行 ant，这一切都可以正常工作。当我尝试从单个 makefile 执行所有操作时，我只收到此 JAVA_HOME not defined correctly 错误。

我需要在不同的机器上 运行 执行此操作而无需执行任何额外配置，并且无法确认 Java 在这些机器上的位置 - 我能得到的唯一保证是Java 已安装并且环境变量有效。
即使您通过 windows 安装程序安装了 Java and/or ant，您仍然需要 set your environment variables. 确保链接 java JDK 而不是 JRE，我作为新手的猜测是，当您编译自己的代码时，您应该始终使用 JDK，因为它具有您需要的所有工具。
只是回答让你标记为已解决。
即使您已经使用 oracle 安装程序安装 Java，您仍然需要创建环境变量。
