java - fail in "mvn clean install"? -

-

I'm new to learning Java programming! I want to make a gazer in a Maven project. After running this command, mvn clean install , I get the following error message:

The target org.apache.maven.plugins failed to execute: maven-compiler -plugin: 2.3.2: Unable to detect JAVAK compiler in project wps-demo (default-compile): compilation failure

: C: \ Program Files \ Java \ jre7 .. \ Lib \ tools jar

Please make sure that you are using JDK 1.4 or above and do not require a JRE (com.sun.tools.javac.Main class) In most cases you

P>

As your error, you are wrong in the system settings in the JAVA_HOME variable The value is ... something like C: \ Program Files \ Java \ jre6

how you can set it for example.

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge.
