运行ant命令时发出

Question

I installed ant in my system, when I run ant command, I get following error:

Error: JAVA_HOME is not defined correctly. We cannot execute /usr/lib/jvm/java-6-sun/bin/bin/java

Please suggest what should I do?

Answer 1

Set the environment variable JAVA_HOME to the installation directory of your JDK, which is: /usr/lib/jvm/java-6-sun

It looks like you have set it to /usr/lib/jvm/java-6-sun/bin (note the /bin at the end); the ant command appends another /bin so that you get .../bin/bin/java which is incorrect.

Answer 2

In your Java installation directory, u can see a jre subdirectory that contains the bin directory that contains java and related executables.

So you should probably be setting JAVA_HOME to /usr/lib/jvm/jdk/jre rather than /usr/lib/jvm/jdk.
