安裝3.0.3

1. 到http://maven.apache.org/download.html下載maven 3.0.3
2. 將apache-maven-3.0.3-bin.tar.gz解壓縮到/usr/share/java
3. 移除/usr/share下的softlink maven
4. ln -s /usr/share/java/apache-maven-3.0.3 /usr/share/maven
5. 修改~/.profile 設定M3_HOME=/usr/share/java/apache-maven-3.0.3
   
   

   注意事項

   不能同時設M2_HOME與M3_HOME兩個環境變數, 不然執行maven會出現以下的exception

   Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/plexus/classworlds/launcher/Launcher  Caused by: java.lang.ClassNotFoundException: org.codehaus.plexus.classworlds.launcher.Launcher   at java.net.URLClassLoader$1.run(URLClassLoader.java:202)   at java.security.AccessController.doPrivileged(Native Method)   at java.net.URLClassLoader.findClass(URLClassLoader.java:190)   at java.lang.ClassLoader.loadClass(ClassLoader.java:307)   at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)   at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
