[jbosstools-issues] [JBoss JIRA] (JBDS-4184) Can't update/install plugins

[Nick Boldt (JIRA)]

    [ https://issues.jboss.org/browse/JBDS-4184?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13324029#comment-13324029 ] 

Nick Boldt commented on JBDS-4184:
----------------------------------

The snapshots site should not be listed by default - only the stable site appears OOTB. So this is intentional.

As to why Eclipse is broken on restart, it's because you installed features you shouldn't have, which drag in dependencies which are already installed via RPM and which therefore conflict:

Dupe plugins:

* /opt/rh/rh-eclipse46/root/usr/share/eclipse/droplets/linuxtools-docker/eclipse/plugins/slf4j.api_1.7.4.jar (newer)
* /opt/rh/rh-eclipse46/root/usr/share/eclipse/droplets/webtools-sourceediting/eclipse/plugins/org.apache.xml.resolver_1.2.0.v200806030312.jar (older)
* /opt/rh/rh-eclipse46/root/usr/share/eclipse/droplets/mylyn-commons/eclipse/plugins/org.apache.commons.lang_2.6.0.jar (???)
* /opt/rh/rh-eclipse46/root/usr/share/eclipse/droplets/webtools-javaee/eclipse/plugins/org.apache.xml.serializer_2.7.1.v200806030322.jar (older)
* /opt/rh/rh-eclipse46/root/usr/share/eclipse/droplets/usage/eclipse/plugins/org.jboss.tools.usage_2.2.1.v20161026-1707.jar (older)

So, you should be installing only the rpm.feature, not the rpmdeps.feature.

But why it's not available as an update is... an excellent question.

> I tried "Check for Updates" in DevStudio 20161116.1305 and 20161113.1010. I used this update site:
> [1] https://devstudio.redhat.com/10.0/snapshots/updates/
> Eclipse was not able to detect any updates (I got "No updates were found" message).
> Then I tried to install plugins using "Install new software".
> Install new software->select Bring Your Own Eclipse->next->restart
> Eclipse didn't detect any problems or conflicts during installation but after restart I got a lot of errors and eclipse didn't start.

>  [^rh-eclipse46-devstudio10.2.log.20161113.1010_update.txt] 
> I also noticed there isn't update site [1] by default after installation. I had to add it.
