Project fails to build in IntelliJ IDEA because cannot load OSGI plugin #54
Comments
How do you import the project in your IDE ? If I import it as a Maven projet I don't have any issue. |
Yes, I originally imported as a Maven project. If I try again from scratch as a new user would after cloning the project, I get a further issue: Error:(26, 16) java: cannot find symbol This I guess is because the service proxy classes need generating. This is going to confuse users. I think it's important that users can get going with vertx-examples straight away without any extra steps, as this will be the first thing they see in Vert.x |
So, this issue is 'expected', we discussed it with @vietj. |
As long as the user can get an example working like the following, I don't mind:
There should be no other steps imho. If a user gets stuck with a cryptic error trying to run the simplest helloworld example they may just walk away from Vert.x and never come back again. |
I've changed the service proxy example in f41e5e6. I've tried the process you mention and it works for me. |
If I git clone, import, and rebuild project I still get: can't find ProcessorServiceVertxEBProxy |
As the classes are generated at compile time when compiling with Maven, IDEs cannot find them.
Oupsy, forgot this reference. |
Thanks, that solves the issue of the build failing for the service proxy example, but now I see the original issue again: Error:osgi: [osgi-examples] Failed to load plugin org.apache.felix.ipojo.bnd.PojoizationPlugin;, error: org.apache.felix.ipojo.bnd.PojoizationPlugin not found, parent: java.net.URLClassLoader@45ee12a urls:[] exception:java.lang.ClassNotFoundException: org.apache.felix.ipojo.bnd.PojoizationPlugin |
I'm going to install a new instance of intellij as I cannot reproduce that one. |
I am using 14.0.3 btw |
Just a guess - maybe you have manually installed some kind of OSGI plugin in your IDE, that I don't have, and is required for this example? |
No, I'm a purist ;-) OSGi does not require any IDE plugin. However, Intellij enables one by default that generally messes up things... I'm downloading community and ultimate. It needs to work out of the box on both. |
Clement - I have license keys for ultimate that you're entitled too, just sent you a private email. |
Ok, I've reproduced the issue, it's the intellij OSGi support (osmorc) that is unable to load BND plugins. I'm looking into it. |
I've moved the osgi-examples to their own profile (not enabled by default). This fixed the Intellij issue. So, the issue is in Osmorc the OSGi plugin of intellij unable to read the configuration (as it is intended to do). The main issue is that it does not support the plugin's dependencies and fails to create the right classloader to execute BND. So the commit is just a work around this issue. |
Ok, I guess this should just be closed then. |
Ok :-) Wanted to add the link to the osmorc bug once opened. |
Here is the Osmorc bug ticket: |
Project... rebuild all gives:
Error:osgi: [osgi-examples] Failed to load plugin org.apache.felix.ipojo.bnd.PojoizationPlugin;, error: org.apache.felix.ipojo.bnd.PojoizationPlugin not found, parent: java.net.URLClassLoader@45ee12a7 urls:[] exception:java.lang.ClassNotFoundException: org.apache.felix.ipojo.bnd.PojoizationPlugin
This means I can't run the examples in the IDE
