Hi,
I am using Maven 1.0.2. I have performance problem. I think it is caused
by reactor semantics.
I am executing the original goal for creating multi jar files. My goal
use "reactor" for executing jar goal throw multi project.
When I executed my goal for creating 244 jar files ,the performance was
grew worse from jar goal to jar goal. I took a long time in jar:jar
semantics.
I checked GC of java and CPU ,but these have no problem. And I took
three thread dumps per 5 sec. I guess it is caused by the logic of goal
chain in reactor semantics.
If you have some information or solution ,please help me.
