Lukáš Valach commented on JBDS-4183:
------------------------------------

I tried to verified this ticket in 10.2-0.20161121.0756. I am able to install *Maven Integration for Eclipse JDT APT (m2e-apt)* and restart eclipse without errors. 

I also tried to verify this as Nick wrote in his guide but I have had problems here. Shoud this fix only solves problem with "Maven Integration for Eclipse JDT APT"? Is expected that I can't go throught all ten steps of Nick's guide without errors?

There are results of my attempt to do it as Nick wrote:

# install from latest rpm (/) (10.2-0.20161121.0756)
# Help > Install New > https://devstudio.redhat.com/10.0/snapshots/updates/ NOT from STABLE or Central (/)
# uncheck "group items by category" (/)
# select cordovasim feature (v20161115 or newer) (/)
# restart when prompted (/)
*no errors in the log*
# ll ~/.eclipse/org.eclipse.platform_*_linux_gtk_x86_64/plugins

Should not see anything from java.servlet(.api)(/), org.apache.httpcomponents.httpclient(.cache)(/)
But will likely see org.slf4j.api 1.7.2 (x), which is probably OK as it's needed by other slf4j jars in the devstudio rpm install
  
7. install the rpm feature to update everything in devstudio to latest snapshot version from https://devstudio.redhat.com/10.0/snapshots/updates/


Then I restarted eclipse and I got errors. I noticed the restart is not mentioned in the quide. Was it intended?
 [^RPM_Fratures_and_restart.txt] 

When I tried it without restart between steps 7 and 8. I got this output after eighth step:
{code}
[lvalach at localhost ldd]$ ls ~/.eclipse/org.eclipse.platform_*_linux_gtk_x86_64/{plugins,features} | egrep -v "org.jboss.tools|org.eclipse.thym|org.jboss.ide|hibernate|com.jboss.devstudio"

There isn't org.slf4j.api package as we wanted.

> Steps to repro:
> 1. install from latest rpm, eg., 10.2.0.20161116.1342.el7
> 2. open Central > Software/Update, scroll down until you find the *Maven Integration for Eclipse JDT APT (m2e-apt)* connector
> 3. Install it. When prompted to restart, shut down Eclipse and check in your ~/.eclipse folder:

> ... the result of this install is to cause use constrain violations and break the devstudio install.
> A bigger problem occurs in JBDS-4150 when installing Thym or Aerogear features, since a second version of org.apache.httpcomponents.httpclient_4.3.6.v201511171540.jar is installed even though there's already one in the /opt/rh/ install footprint.
