Importing Bazel built ONOS 1.14 or higher into Intellij

[Andrea Campanella]

Hi ONOS developers,

As you know since ONOS version 1.14 the ONOS project moved to Bazel and the use of BUILD files. In version 1.15 (current Master) we have already dropped completely the pom.xml files from the codebase. 

For you to develop using Intellij and the newest version of ONOS we wrote a page on how to import a Bazel based project into the IDE. You can find it here:

https://wiki.onosproject.org/pages/viewpage.action?pageId=28836246

For more information about Bazel and how to Build ONOS with it please visit the wiki (wiki.onosproject.org) or follow the TST meeting:

Video: https://www.youtube.com/watch?v=fz5iGhGVz4c&feature=youtu.be 

Slides: https://docs.google.com/presentation/d/1ghc1kGIwdkah6nACFofm3s5e731CZmmBPM-V21b_1Bc/edit#slide=id.p 

I hope this helps you and empowers you to continuously create new great ONOS code and use cases. 

Please do not hesitate to try all of this out and ask any question you might have.

Looking forward to your contributions,

Happy coding!

Great notes - Thanks. And great to see the end of the pom.xml files.

I couldn't find anything on the Wiki that says the Bazel version has to be 15.2 though, like Thomas had in his original mail at

https://groups.google.com/a/onosproject.org/d/msg/onos-dev/nk65O5JELMY/R8jSyvDNCwAJ

[Andrea Campanella]

Hi Sean,

Thanks for pointing that out. I’ve updated the wiki here

https://wiki.onosproject.org/display/ONOS/Developer+Quick+Start

With a warning to specify bazel 0.15.2.

Thanks,

Hi Andrea,

Thanks for the great tutorial, much appreciated!

Could you please add one more sentence on how to clean before a build?

With BUCK this was: rm -rf buck-out bin && onos-buck clean.

What is the Bazel counterpart of this command?

Thanks,

Georgios

Great idea! To completely clean your bazel caches and restart the bazel server, you can use:

bazel clean --expunge

In my experience with bazel, it does an excellent job of tracking dependencies and cleans are rarely needed. I did have to do them a few times while developing new rules, before all of the dependencies are right.

Hello everyone,

After importing the onos codebase to intellij as a bazel project, there is a problem with which folder should be the sources root. Can anyone please tell  me that? 

Otherwise it is showing package name does not correspond to file path. Though I have imported the setting from onos/tools/dev/ideasettings.jar

[Carmelo Cascone]

Source directories should be automatically derived form the bazel targets declared in the .bazelproject file.

have already followed the steps in this page to automatically generate a .bazelproject file?

I have followed this steps described on the link. But not working. Tried to sync the bazel project with bazel files and it shows several errors. but bazel build succeeds and onos runs perfectly. 

first error is 

ERROR: /home/deba/p4-guide/onos/BUILD:133:11: in cmd attribute of genrule rule //:onos-local_absolute-javabase: $(ABSOLUTE_JAVABASE) not defined

 

I am using java 11. I have imported the onos project successfully according to the steps earlier. But this time, its not working.

I have setup the java_base in the bazelrc file. that solved the first problem of java_base but I have no clue about the rest of the problems. 

While trying to sync the project with bazel file I am getting error of following type

ERROR: /home/deba/p4-guide/onos/providers/lldp/BUILD:10:1: Couldn't build file providers/lldp/onos-providers-lldp-native.java-manifest: Parsing java package strings for //providers/lldp:onos-providers-lldp-native failed (Exit 1) PackageParser_bin failed: error executing command bazel-out/host/bin/external/intellij_aspect/PackageParser_bin --output_manifest bazel-out/k8-fastbuild/bin/providers/lldp/onos-providers-lldp-native.java-manifest --sources ...

Hi,

i think this error is caused either by the new Intellij IDE or the bazel plugin. I had the same problem while importing the project. I am using v2019.2.4 of Intellij IDE and bazel plugin 2019.10.14.0.0. It worked for me.  

check this https://groups.google.com/a/onosproject.org/d/msg/onos-dev/EzNjzH_Z27E/l-ubqIM6FAAJ

[Dũng Nguyễn Tiến]

Excuse me, a marginal question. I need setup an enviroment to process transport layer, but i don't know how to do that.  (app 

Reactive Forwarding-org.onosproject.fwd only forward packet layer 2) 

Thanks,

[Hadi Kahraman]

From my notes for ONOS 1.15:

Install IntelliJ idea-IC-183.6156.11, *** 2018.3, NOT THE LATEST VERSION***
Install "Bazel" plugin to Idea: file -> settings -> plugins

Hi, 

I have same problem with you. When I 'expand synch to working set' , I get the error "ERROR: /home/jku/onos/BUILD:138:8: in cmd attribute of genrule rule //:onos-local_absolute-javabase: $(ABSOLUTE_JAVABASE) not defined".  And when not expanding to working set, It is synced with no problem.

Can you tell me how you setup javabase in bazelrc file ? 
I really want to get through this stuff. I googled a lot, and only solution I found was yours 

Please share your java_base solution to me~ 

Thanks for reading 

Best,

Jkkr
