Maven Unable to locate the Javac Compiler in:

Asked 2012-09-25T14:42:00.597

When i try to generate a war file, it is showing some error like

[ERROR] Unable to locate the Javac Compiler in:
[ERROR] C:\Program Files\Java\jre7\..\lib\tools.jar

When i do echo %path% it shows

 C:\Windows\System32;D:\name\name1\Softwares\Maven\apache-maven-3.0.4\b
in;C:\Program Files\Notepad++\;%JDK_HOME%

When i do echo %JDK_HOME%

D:\name\name\core java\software\Java\Java_1.6.0_04_win\jdk1.6.0_04\bin

I don't know why maven is refering to jre, when my environmental variable is jdk. I also changes installed JRE to jdk1.6.

java maven javac

Go to Window -> Preferences... -> Java -> Installed JREs

Edit JRE Home = JAVA_HOME or JAVA_HOME\jre

For example if you use jdk1.6.0_04 which is installed in C:\Program Files, do the following change:

C:\Program Files\Java\jdk1.6.0_04\jre or C:\Program Files\Java\jdk1.6.0_04 instead of the default one which is at C:\Program Files\Java\jre7

It was an Eclipse problem. When I tried to build it from the command line using

mvn package

it worked fine.
