Re: [osgi-dev] enroute quickstart tutorial problems - New Bnd OSGi Workspace - Distro->org.osgi:osgi.enroute.pom.distro [!]->2.0.0.SNAPSHOT [java.lang.NullPointerException]

We are moving to https://github.com/osgi/enroute.workspace/ as the EnRoute workspace. Bndtools 3.4 will use it.

> It should be without the SNAPSHOT. Can you recall how the -SNAPSHOT got in there?
 
The "-SNAPSHOT" came from the osgi/workspace GitHub Repository.
 
When I did 
 
1. Eclipse->File->New->Other
2. Eclipse shows New->Select a wizard"
3. Selected Bndtools->Bnd OSGi Workspace and clicked Next.
4. Eclipse shows "Setup Bnd Workspace".
5. Click Location->Create in->c:\dev\git\com.acme.prime and clicked Next.
6. Eclipse shows "Selecte Workspace Template".
7. Selected GitHub->osgi/workspace [https://github.com/osgi/workspace.git next] and clicked Next.
8. Eclipse shows Preview Changes.
9. Clicked Finish.
10. Eclipse creates a cnf project and switches to Bndtools Perspective.
 
The bnd project created by Eclipse already contains the erroneous "-SNAPSHOT" in cnf/ext/enroute-distro.bnd.  I think it's getting downloaded from 
 
 
the current revision https://github.com/osgi/workspace/commit/862f1d9bc0b6ad79ef578c85503ef17f54d60bda has an -plugin.enroute.distro entry with the "-SNAPSHOT" text. Doing Blame on that file shows it has had that -SNAPSHOT for 7 months.

On the current workspace the bndpom repo looks like:
 
-plugin.enroute.distro = \

It should be without the SNAPSHOT. Can you recall how the -SNAPSHOT got in there?
 
Kind regards,

I'm trying to follow the Enroute Quick Start Tutorial.  But I got stuck with this build error
 
Cannot find /error/osgi.enroute.base.api;version=0 Not found in [bnd-cache, Central, Local, Release, Distro]
 
I don't know how to fix this problem.  I think the root cause is that the Distro repository seems to be invalid.
 
What is the correct cnf/ext/enroute-distro.bnd?  The steps in the tutorial resulted in an enroute-distro.bnd that looks like
 
-plugin.enroute.distro = \
aQute.bnd.repository.maven.pom.provider.BndPomRepository; \
revision=org.osgi:osgi.enroute.pom.distro:2.0.0-SNAPSHOT; \
name=Distro; \
location=${build}/cache/enroute-distro.xml
 
I found some August 2016 information here https://disqus.com/home/discussion/osgi-enroute/forum_49/ suggesting using the URL https://raw.githubusercontent.com/osgi/osgi.enroute/master/cnf/distro/index.xml.  But using that location didn't work either.
 
********Below I'm documenting what I did and some of the errors I'm noticing....*************
 
I noticed in this page
 
http://enroute.osgi.org/qs/200-workspace.html
 
this text
 
"WARNING: This is the BETA tutorial for OSGi enRoute 2.0.0. To use the right workspace template, go to Bndtools preferences and select Workspace Templates. You should edit the OSGi enRoute template and select the next branch."
 
In response to this text, I completed these steps.
 
1. Eclipse->Preferences->Bndtools->Workspace Template->GitHub Repositories
2. Click osgi/workspace
3. Click Edit.
4. In the Add Repository tab entered these values
Repository Name: osgi/workspace
Branch: next
5. Click Validate.
6. Eclipse confirms with "Validated! Clone URL is 'https://github.com/osgi/workspace.git'. Default branch 'origin/master'"
7. Click Save.
8. Eclipse updates osgi/workspace to read "osgi/workspace; branch=next".
 
Then I executed the steps in the "Creating the bnd Workspace" section of 200-workspace.html.  After clicking "Finish" in the workspace creation Wizard.  I noticed that the Eclipse "Repositories" view contains a Distro that appears to have a problem.  Expanding the Distro repository reveals
 
Distro->org.osgi:osgi.enroute.pom.distro [!]->2.0.0.SNAPSHOT [java.lang.NullPointerException]
 
The Eclipse Error Log view contains
Failed to query repository Distro for bundle org.osgi:osgi.enroute.pom.distro version 2.0.0.SNAPSHOT.
 
Eclipse plugin: bndtools.core
