从Java编译maven项目

Question

在我的java代码中，我想编译一个maven项目（mvn clean install）。如何在不制作Runtime.getRuntime().exec()的情况下完成这项工作？

Answer 1

让我们看看......

$ which mvn
/usr/bin/mvn

$ cat `which mvn`
... lots of code ending with...
exec "$JAVACMD" \
  $MAVEN_OPTS \
  -classpath "${M2_HOME}"/boot/plexus-classworlds-*.jar \
  "-Dclassworlds.conf=${M2_HOME}/bin/m2.conf" \
  "-Dmaven.home=${M2_HOME}"  \
  ${CLASSWORLDS_LAUNCHER} "$@"

$ cat `which mvn` | grep CLASSWORLDS
CLASSWORLDS_LAUNCHER=org.codehaus.plexus.classworlds.launcher.Launcher
  ${CLASSWORLDS_LAUNCHER} "$@"

所以我相信你需要运行org.codehaus.plexus.classworlds.launcher.Launcher.main(new String[] {"clean", "install"})。 YMMV。
