Build failure when trying to create new app with onos-create-app

[Daniela Maria Casas Velasco]

Hi everyone,
I am following the tutorial in https://wiki.onosproject.org/display/ONOS/Template+Application+Tutorial to create a new app but I have been not able to pass the very fisrt step.
After I run onos-create-app app org.foo foo-app 1.0-SNAPSHOT org.foo.app, I get the following error:

I installed onos locally and it built with success, the erros appears when trying to creat new apps.
I am using onos 2.7.0
maven 3.3.9


I'll really appreaciate if someone can give me an inside of how to solve this.
Thanks

Hi Daniela,

Could your share your pom.xml file?

[Daniela Maria Casas Velasco]

Hi Davide,
Sorry, I do not understand to which pom.xml you're referring at.
I run the command when I'm located in the home of my terminal ans then the error appears, and it's always the same.
Any advice? Thanks

[0ice...@gmail.com]

Hi Daniela,

I don't undestand if you have a problem of versioning related to the maven  the artifacts. More in details,  before to use the command onos-create-app you should run the command export ONOS_POM_VERSION=your onor version-SNAPSHOT . Then you can run the code  onos-create-app app org.foo foo-app 1.0-SNAPSHOT org.foo.app.

You can also try to run  those commands :

•  in /onos/tools/package/archetypes you have to run mvn clean install 
• in /onos you have to run  onos-publish -l  and after that you should run onos-create-app bla bla .

When you create an onos app via the command a pom.xml file should be generated, it contains all the Maven dependencies needed by your application.

Hi Davide,
I had already tried doing mvn clean install in the archetypes folder but I had errors.
Then I did define ONOS_POM_VERSION by trying with both:
   $ export ONOS_POM_VERSION=2.7.0
   $ export ONOS_POM_VERSION=2.7.0-SNAPSHOT
but in both cases, when I run mvn clean install  in /onos/tools/package/archetypes
I get another error as follows:

Hi Daniela,

• did you create the onos app outside the onos folder, rigth?
• you should try to run mvn clan install -X for have te full visibility of what it's going on, but is hard to undestand whtas going on

I think that you have messed up in some way the onos folder or the archetipes folder, It's hard to say because the pom that you are donwloading is referred to version 3.0.0 (the last version)  https://repo.maven.apache.org/maven2/org/onosproject/onos-base/1/onos-base-1.pom but you are working with the 2.7.0. 

Could you try to run git branch -a and tell me wich is the version pointed by the *? Did you donwloaded the last version of onos?

Hi Davide,
  - Did you create the onos app outside the onos folder, rigth?
                  yes, I tried to create the app outside the onos folder.

   - You should try to run mvn clan install -X for have te full visibility of what it's going on, but is hard to undestand whtas going on

                 Here's the output by running -X in command:

I think that you have messed up in some way the onos folder or the archetipes folder, It's hard to say because the pom that you are donwloading is referred to version 3.0.0 (the last version)  https://repo.maven.apache.org/maven2/org/onosproject/onos-base/1/onos-base-1.pom but you are working with the 2.7.0. 

Could you try to run git branch -a and tell me wich is the version pointed by the *? Did you donwloaded the last version of onos?

Ok, I guess I think what is the problem related to, but I do not understand hat happened.

In the very fisrt time I startet with onos, I dowonloaded the last version in the repository (3.0.0), but I got some erros in the same step I am having errors now (when using onos-create-app).

Then I decided to use the last released version instead the one in the repository, that is why I switched to 2.7.0, so I deleted the onos folder, and cloned the repository again, this time with git checkout 2.7.0 , hoping that I wouldn't find too much building or compilation errors.
Do I have to delete any other folder or things for switching from onen ONOS version to another, I don't know if somehow things got mistured :(, sorry I am still understanding how ONOS works...

Hi Daniela,

I believe that is a problem of versioning, imho something is messed up. But this is my idea.

In the very fisrt time I startet with onos, I dowonloaded the last version in the repository (3.0.0), but I got some erros in the same step I am having errors now (when using onos-create-app)  

I didn't undestant what was the problem. But you can try to delete the onos folder in .m2 folder and doing mvn clean install.

My suggestion is delete the onos folder and reinstall evething, then you can show us the error thet you get when you creating the onos app in 3.0.0.

best

Hi Davide,

I just wanted to let you know that know it worked. I trully think that the problem was related to versioning dependencies as you suggested.
I wanted to continue working with 2.7.0 so I restarted the installation process in a new VM.
Just to let a record of what worked for me to solve the errors, this time I installed Onos locally with:
- Ubuntu 20.04.4 LTS

- Onos 2.7.0 (cloned the repository and git checkout 2.7.0)
- Maven 3.3.9
- Java openjdk 11
- Bazelisk version: v1.4.0 (build label 3.7.2)

Thanks for your time and suggestions!
