Subject [jira] Commented: (CONTINUUM-2424) Getting ".../mvn version return code 1" error when trying to add maven2 installation.
Date Thu, 07 Jan 2010 01:02:55 GMT

    [ http://jira.codehaus.org/browse/CONTINUUM-2424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=205469#action_205469
] 

Igor Grapp commented on CONTINUUM-2424:
---------------------------------------

"java.home" system property points JAVA_HOME that java app started with. It is loaded implicitly
by jvm and it could be retrieved by code snippet -  "String javahome = System.getProperty("java.home"
);

See http://java.sun.com/j2se/1.5.0/docs/api/java/lang/System.html#getProperties() for more
info.

Reporduction steps:

1. In windows, right click on "My Computer", navigate to "Advanced" tab and click "Enviromental
Variables" button.
2. remove JAVA_HOME variable(s).
3. Install continuum as a service.
4. Install maven 2 at c:\temp\apache-maven-2.0.10.
5. Start continuum as a service.
6. Open browser, login into continuum and add new installation.
7. Select "maven2" type.
8. Enter c:\temp\apache-maven-2.0.10 as a path.
9. Hit submit button - you will get an error described.

> Getting ".../mvn version return code 1" error when trying to add maven2 installation.
> After quick debugging session, I discovered that this happens due to JAVA_HOME was not
set as a system env variable and "mvn" script requires it to be set before running.
> I guess that "JAVA_HOME" env variable need to  explicitly set in org.apache.maven.continuum.web.validator.InstallationValidator
with value taken from  "java.home" system property.
> Also, I would recommend to output stderr stream to the log during error, since this will
clearly indicate an error with no need for debugging session.
