JAVA_HOME 不指向 JDK

JAVA_HOME does not point to the JDK(JAVA_HOME 不指向 JDK)

问题描述

我正在尝试学习有关如何使用 ant 构建和运行您的应用程序的教程.我已经按照所有步骤创建了构建文件，但是当我尝试运行 ant 时，它给了我这个错误.

I am trying to follow a tutorial about how to use ant to build and run your application. I've followed all the steps and have created the build file, but when I try to run ant it gives me this error.

构建失败/home/bilal/tmp/ant/build.xml:19:找不到javac编译器；com.sun.tools.javac.Main 不在类路径中.也许 JAVA_HOME 不指向 JDK.当前设置为/usr/lib/jvm/java-6-openjdk/jre"

BUILD FAILED /home/bilal/tmp/ant/build.xml:19: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "/usr/lib/jvm/java-6-openjdk/jre"

任何想法如何解决这个问题?

Any ideas how to resolve this issue ?

推荐答案

使 JAVA_HOME 变量指向 jdk 安装，而不是 jre.

Make JAVA_HOME variable point to a jdk installation, not jre.

您引用的是运行时环境，而不是开发工具包——它找不到编译器，因为它不存在.

You are referencing the runtime environment, not the development kit - it can't find the compiler because its not there.

从您发布的行中，您可以在末尾删除 jre:

From the line you posted, which states you have open-jdk you can just remove the jre at end:

export JAVA_HOME='/usr/lib/jvm/java-6-openjdk/'
