linux - 无法在 : 中找到 Javac 编译器

Question

我已经按照下面的指导安装了 OpenJDK。但我仍然不断收到此错误。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？

 [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-     plugin:2.3.2:compile (default-compile) on project poker-protocol: Compilation failure

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

有人可以帮帮我吗？

您已经安装了 Java 运行时，但是要开发 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 。
