Question

我已经安装了OpenJDK，如下所述。但我仍然继续得到这个错误。我在bash_profile中设置了正确的PATH。

有人可以帮我解决这个问题吗？

在我的bash_profile中我有这个：

 JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre
 export M2_HOME=/usr/local/apache-maven-3.0.4
 export PATH=${M2_HOME}/bin:${PATH}:$JAVA_HOME/bin

有人能帮助我吗？

Answer 1

您已经安装了Java运行时，但是要开发Java应用程序需要JDK，因此必须安装OpenJDK开发包，在您的情况java-1.6.0-openjdk-devel-1.6.0.0.x86_64中。

Answer 2

不太确定，但就我而言，我已经这样设置了：

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_11/
export PATH=$JAVA_HOME/bin:$PATH

我已在bash.bashrc

中完成此操作

在提供变量名称之前尝试添加export。我发现甚至认为我没有使用openjdk的另一件事是，tool.jar不在jre目录中，而是在jdk目录下。

希望这有帮助。

Answer 3

你需要安装 java-1.6.0-openjdk-devel 安装java-1.6.0-openjdk只需安装JRE。

无法找到Javac编译器：
