RE: need help on maven compile phase.
You have to restructure your project. Like: module-name-pkg1/src/main/java/com/abc/xyz/pkg1 module-name-pkg1/src/test/java/com/abc/xyz/pkg1 module-name-pkg1/pom.xml module-name-pkg2/src/main/java/com/abc/xyz/pkg2 module-name-pkg2/src/test/java/com/abc/xyz/pkg2 module-name-pkg2/pom.xml module-name-pkg3/src/main/java/com/abc/xyz/pkg3 module-name-pkg3/src/test/java/com/abc/xyz/pkg3 module-name-pkg3/pom.xml module-name-pkg4/src/main/java/com/abc/xyz/pkg4 module-name-pkg4/src/test/java/com/abc/xyz/pkg4 module-name-pkg4/pom.xml pom.xml The aggregate pom (now your main pom) should contain a modules section, like: module-name-pkg1 module-name-pkg2 module-name-pkg3 module-name-pkg4 After that you would want your dependencyManagement in your aggregate pom and add a section to your module pom files. Then strip all version numbers in the dependencies section in your module poms and add them to the dependencyManagement section. All in all, a fairly big refactoring, but take a good look at the book at sonatype. All the elements are explained there. Hth, Nick Stolwijk ~Java Developer~ Iprofs BV.

Re: need help on maven compile phase.
there are indeed seperate test classes for all those packages. but what i m not understanding is how do i write seperate poms for each pakage. and where do i kep that pom? and how do i call it? right now I am using one pom in the prj_home dir.

Re: need help on maven compile phase.
The easiest way is to split your sources into separate maven modules. If you have 1600 classes, this imho makes sense anyway! I (personally) mean, if a project is _that_ fat, then a modularisation would help to better understand the whole application. Each modules should have their own unit tests, etc. Simply, the whole bunch of straight forward computer engineering rules one learns in university.

Re: need help on maven compile phase.
The general concept with Maven would be that you should divide your code up into "modules" along whatever lines that make sense to you (1 module per pkg may be reasonable for your specific implementation, I suppose). Then you set up dependencies between the modules via each one's pom.xml file, and perhaps establish a "parent" which encompasses all modules. This would be set up like: parent/pom.xml parent/pkg1/pom.xml parent/pkg1/src/main/java/com/abc/xyz/pkg1 parent/pkg2/pom.xml parent/pkg1/src/main/java/com/abc/xyz/pkg2 parent/pkg3/pom.xml parent/pkg1/src/main/java/com/abc/xyz/pkg3 parent/pkg4/pom.xml parent/pkg1/src/main/java/com/abc/xyz/pkg4 So you would have probably 5 pom.xml files if you implemented this. You should do some reading (Better Builds With Maven etc) and look at sample projects (many open-source projects use Maven, and you can browse their code repositories to see how things are laid out and check out their pom.xml files) to see how this might apply to your specific situation.

Re: need help on maven compile phase.
I tried increasing the memory using the maxmem and memintial, initial=512mb and mac=2048m. still the same error. my 1642 files have been distributed accross four packages. src/main/java/com/abc/xyz/pkg1 pkg2 pkg3 pkg4 whould i write seperate POMs for each pkg? where should these POMs be present. then what about the main POM in the prj_home/dir?

Re: need help on maven compile phase.
Actually, I can think of seperate module inside the main root project and a seperate pom.xml for each one. Then you can build those one by one. Else, try increasing the memory with the compiler plugin (I think, you have atleast 1.5 GB RAM) org.apache.maven.plugins maven-compiler-plugin 512m 1024m This may resolve the out of memory error.
