如何使用无头P2安装M2E-WTP

Question

I have this problem I've been struggling with for a while. I want to install Eclipse plugins automatically during an automated Eclipse installation process. So far I've been able to install the following over fresh eclipse-jee-juno-SR1-linux-gtk-x86_64.tar.gz:

./eclipse -nosplash \
  -application org.eclipse.equinox.p2.director \
  -repository http://dist.codehaus.org/groovy/distributions/greclipse/snapshot/e4.2/ \
  -installIU org.codehaus.groovy.jdt.patch.feature.group \
  -installIU org.codehaus.groovy.eclipse.feature.feature.group \
  -installIU org.codehaus.groovy17.feature.feature.group \
  -installIU org.codehaus.groovy18.feature.feature.group \
  -installIU org.codehaus.groovy20.feature.feature.group \
  -repository http://download.eclipse.org/technology/m2e/releases \
  -installIU org.eclipse.m2e.feature.feature.group \
  -repository http://repo1.maven.org/maven2/.m2e/connectors/m2eclipse-mavenarchiver/0.15.0/N/0.15.0.201207090125/ \
  -installIU org.sonatype.m2e.mavenarchiver.feature.feature.group \
  -repository http://repo1.maven.org/maven2/.m2e/connectors/m2eclipse-buildhelper/0.15.0/N/0.15.0.201207090124 \
  -installIU org.sonatype.m2e.buildhelper.feature.feature.group \
  -repository http://download.jboss.org/jbosstools/updates/m2e-extensions/m2e-apt \
  -installIU org.jboss.tools.maven.apt.feature.feature.group \
  -repository http://download.jboss.org/jbosstools/updates/m2e-extensions/m2e-jdt-compiler/ \
  -installIU org.jboss.tools.m2e.jdt.feature.feature.group

All is nice but when I try to import a Groovy, Maven-managed web application project Eclipse starts complaining about missing m2e-wtp being missing. Now here's the real issue. I can install it either using UI (which is what I don't want) and then it works but tries to install both org.jboss.tools.maven.apt.feature.feature.group and org.jboss.tools.m2e.jdt.feature.feature.group once again and then the missing org.eclipse.m2e.wtp.feature.feature.group. When I install it using P2 as follows

./eclipse -nosplash \
  -application org.eclipse.equinox.p2.director \
  -repository http://download.eclipse.org/m2e-wtp/releases/ \
  -installIU org.eclipse.m2e.wtp.feature.feature.group \

nothing works anymore even Eclipse does not find anything on the Eclipse Market.

Can someone shed some light on how to install those dependencies properly?

Answer 1

I found what the problem was. I have forgotten to add the

org.codehaus.groovy.m2eclipse.feature.group

feature while installing Groovy Eclipse thus there was noting to connect Eclipse and Maven.
