Ant：線程「main」中的異常java.lang.NoClassDefFoundError：org/apache/tools/ant/launch/Launcher

Question

我已經在我的系統中安裝了ubuntu 10.10並使用以下命令安裝了ant： sudo apt-get安裝螞蟻

如今，螞蟻是在共享文件夾可見的，所以我試圖運行終端ant命令，但它給了我這個錯誤：

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. 

然後我重新設置這些：

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

現在它給我同樣的錯誤，但與起點不同的一個行：

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

Answer 1

嘗試以下操作：

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"
