Ant：线程“main”中的异常java.lang.NoClassDefFoundError：org/apache/tools/ant/launch/Launcher

Question

我已经在我的系统中安装了ubuntu 10.10并使用以下命令安装了ant： sudo apt-get安装蚂蚁

如今，蚂蚁是在共享文件夹可见的，所以我试图运行终端ant命令，但它给了我这个错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher 
Caused by: java.lang.ClassNotFoundException: org.apache.tools.ant.launch.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) 
Could not find the main class: org.apache.tools.ant.launch.Launcher. Program will exit. 

然后我重新设置这些：

JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.22/" 
ANT_HOME="/usr/share/ant/" 
PATH="/usr/share/ant/bin/" 

现在它给我同样的错误，但与起点不同的一个行：

/usr/share/ant/bin/ant: 92: uname: not found 
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher

Answer 1

尝试以下操作：

JAVA_HOME="/usr/lib/jvm/java-6-sun" 
ANT_HOME="/usr/share/ant" # do not add "bin" at the end of the path** 
PATH="$ANT_HOME/bin:$PATH"
