[Solved]-Unable to launch Eclipse neon 4.6 - asks for roo distribution-eclipse

according to the roo documentation, you download roo and then point sts to wherever you installed (extracted) it. my understanding is that roo operates in conjunction with the ide, but is a standalone tool.

i installed some default plugins and then the roo plugin kept asking for configuration and couldn't uninstall it from the help menu (because roo was always prompting the configuration menu).

i followed the answer provided here:

$ eclipse -application org.eclipse.equinox.p2.director -listinstalledroots | grep roo
org.springframework.ide.eclipse.roo.feature.feature.group/3.8.3.201612191259-release
org.springframework.ide.eclipse.roo.feature.source.feature.group/3.8.3.201612191259-release

$ eclipse -application org.eclipse.equinox.p2.director -uninstalliu org.springframework.ide.eclipse.roo.feature.feature.group/3.8.3.201612191259-release
$ eclipse -application org.eclipse.equinox.p2.director -uninstalliu org.springframework.ide.eclipse.roo.feature.source.feature.group/3.8.3.201612191259-release
