编译错误

Question

我的工作的Fedora，我的Java家被设定为：

export JAVA_HOME=/home/UserName/java 

    export M3_HOME=/home/UserName/softwares/apache-maven-3.0.3 
    export PATH=$PATH:/home/UserName/java/bin:/home/Udeshika/softwares/apache-maven-3.0.3/bin 

现在，当我尝试运行mvn install Maven的项目，我收到以下错误

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project viewer: Compilation failure 
[ERROR] Unable to locate the Javac Compiler in: 
[ERROR] /home/UserName/java/jre/../lib/tools.jar 
[ERROR] Please ensure you are using JDK 1.4 or above and 
[ERROR] not a JRE (the com.sun.tools.javac.Main class is required). 
[ERROR] In most cases you can change the location of your Java 
[ERROR] installation by setting the JAVA_HOME environment variable. 
[ERROR] -> [Help 1] 
[ERROR] 

如果我检查我的Maven版本

Apache Maven 3.0.3 (r1075438; 2011-02-28 23:01:09+0530) 
Maven home: /home/UserName/softwares/apache-maven-3.0.3 
Java version: 1.6.0_07, vendor: Sun Microsystems Inc. 
Java home: /home/UserName/java/jre 
Default locale: en_US, platform encoding: UTF-8 
OS name: "linux", version: "2.6.34.9-69.fc13.i686.pae", arch: "i386", family: "unix" 

这里行家告诉我的JAVA_HOME是

Java主：/家庭/用户名/ JAVA/JRE

我想我现在已经确定的问题，我不知道解决这个问题任何人都可以引导我解决这个问题？

预先感谢您

您需要有一个Java SDK才能使用Maven。 SDK包含tools.jar并允许您编译，而JRE仅仅是一个运行时。
