Yeah Thanks for the clue.. Everyone is correct. In my JDK version tools.jar was not available thats why I was getting this problem its not finding tools.jar, While JAVA_HOME varible is configured correctly. Need to focus on only Tools.jar so that installed again java version (i am using java 6) Now come on project--> go thru the build path and Make sure---- click on

installed jre edit jre home =C:\Program Files (x86)\Java\jdk1.6.0_25

give path accordingly for which Your OS is compatible

Your JAVA_HOME path is not set. You need to set it as C:\Program Files\Java\jdk <version>

Maven uses JAVA_HOME to access Java's location on the machine. In Your situation You point it to JRE not JDK. Set properly JAVA_HOME environment variable and it will work.

If You want to have different location/version used for Maven only You can edit mvn.bat file with something like this.

set JAVA_HOME=<path_to_other_jdk>

Everything is said in the exception:

Unable to locate the Javac Compiler in: C:\Program Files (x86)\Java\jre6..\lib\tools.jar

Your maven task is trying to "compile" something, but can't find the Java compiler (JDK=Java Development Kit).

Please ensure you are using JDK 1.4 or above and not a JRE.

Instead it finds a JRE=Java Runtime Environment (which is used for running java programs, not compiling them).

you can change the location of your Java installation by setting the JAVA_HOME environment variable

You need to have a valid JDK version installed and your JAVA_HOME environment variable must point to this JDK folder.
