我已经按照下面的指导安装了 OpenJDK。但我仍然不断收到这个错误。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 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

有人可以帮我吗?

您已经安装了 Java 运行时,但要开发 Java 应用程序,您需要 JDK,因此您必须安装 OpenJDK 开发包,在您的情况下java-1.6.0-openjdk-devel-1.6.0.0.x86_64

你需要安装java-1.6.0-openjdk-devel 安装 java-1.6.0-openjdk 只是安装 JRE 。

不太确定,但就我而言,我是这样设置的:

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

我已经这样做了bash.bashrc

export在提供变量名称之前尝试添加。我发现的另一件事甚至认为我没有使用 openjdk,它tool.jar不是位于jre目录中,而是位于jdk目录下。

希望这可以帮助。
