[FIXED] maven build offline error- must specify a valid lifecycle phase

Issue

I am still getting the hang of Maven and spring, but am having an odd problem.

Up until a few days ago I could build maven fine by using the command:

mvn -Dmaven.test.skip=true clean install eclipse:eclipse –o

not sure what changed but i started getting the error:

BUILD FAILURE
Invalid task 'uo': you must specify a valid lifecycle phase, 
or a goal in the format plugin:goal or 
pluginGroupIf:pluginArtifactId:pluginVersion:goal
for mor information run with the -e switch

I tried updating all my code from SVN and got the same error. I finally completed building all packages with online with: mvn -Dmaven.test.skip=true clean install eclipse:eclipse

which gave be BUILD SUCCESSFUL for all project packages.

Yet when I try building maven offline again i continue to get the same Build Failure error. Any thoughts?

Note: there is about 8 packages in my project and they all get the same build failure error

Solution

– character is incorrect use - instead, in your command

change this

mvn -Dmaven.test.skip=true clean install eclipse:eclipse –o

to

mvn -Dmaven.test.skip=true clean install eclipse:eclipse -o

Note: there is change in - hyphen character
