the last method need more memory than the first because All =
project is
launch in the same jvm, and you are some memory leak.

For the second method, the correct syntax is :
     <maven:reactor basedir=3D"${basedir}"
                     includes=3D"${maven.project1.root.dir}/=
project.xml"
                     goals=3D"goal1, goal2...."
                     banner=3D"Deploying project1"
                     ignoreFailures=3D"true"
    />

Objet: <exec ... "maven"...>  vs. <maven:maven...>

hey,

I experimentet with that topic a long time, now I'll ask you=
...

I'd like to run a nightly-build to compile 4 projects, two o=
f them
depend on the two basic projects. For each of them I wrote
maven.xml-files. Then I installed a fifth, a controll-maven-=
project,
which runs the 4 projects, organizes the files, checkout the=
 source,
starting the jboss  and sending a mail etc.=20

Now to the problem:
I testet 3 ways of calling the single projects:


First I tried (for each project):=20
...
    <exec dir=3D"${maven.project1.root.dir}"  executable=3D"=
maven" >=20
  <arg line=3D"goal1 goal2..." />
    </exec>=20
...

That works but it creates always a new process, which I don'=
t like.

Then I thought, I reduce the memory use and the working time=
:
...
     <maven:reactor basedir=3D"${maven.project1.root.dir}"
                     includes=3D"project.xml"
                     goals=3D"goal1, goal2...."
                     banner=3D"Deploying project1"
                     ignoreFailures=3D"true"
    />
...
But this not really works (Error: "please specify a basedir-=
tag" (?))

Then I tryed the maven:maven goal:
...
    <maven:maven
          descriptor=3D"${maven.project1.root.dir}/project.x=
ml"
          goals=3D"goal1, goal2,..."
   ignoreFailures=3D"true"
    />
...
but this aborts during executing the 3th project with an out=
ofmemory
Exception.

Why does the last method need more memory than the first?
That's confusing.

Thanks a lot,

Georg Scherzer
