I’m trying to build some java project in my new pc, got some error:
build.xml:46: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to “C:\Program Files (x86)\Java\jre7”
cannot access java.util.ArrayList
[javac] bad class file: C:\Program Files (x86)\Java\jre7\lib\rt.jar(java/util/ArrayList.class)
[javac] class file has wrong version 51.0, should be 49.0
[javac] Please remove or make sure it appears in the correct subdirectory of the classpath.
[javac] import java.util.ArrayList;
[javac] 1 error
[javac] 100 warnings
I have config the Path environment variable, and the JRE installed in Eclipse preferences, I got those Errors also, and I forget there also need to config the ant run configuration: run as… and switch to ‘JRE’ tab, select the right JDK.
