Is there a way in 3.x to specify multiple features / bundles repos for pom-less builds

[peterkir]

Hi all,

I have a question regarding tycho 3.x and structured builds.
As I was not able to find documentation about it, I'm asking here.
In a complex system, that has for organizational purposes different folders for specific domains containing feature / bundle sets.

pom.xml # parent.pom /feature_domain_A /plugins_domain_A /feature_domain_B /plugins_domain_B /releng ....

Is this feasible and how can it be configured it it is?

The documentation is here please suggest changes if anything is missing:

You can can reference any bundle or feature directly in the <modules> section, beside that, you can reference any folder containing bundles / features in the <modules> section if it is named plugins, bundles or features and all items will automatically be aggregated.

Thx for the doc link,
I tried to specify sub domain modules with
<module>domain1/features</module> <module>domain1/bundles</module>
and with
<module>domain1`
given a "parent-pom"

<project>
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>example.rcp</groupId>
    <artifactId>example.rcp.parent</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>..</relativePath>
  </parent>
  <groupId>example.rcp</groupId>
  <artifactId>example.rcp.domain1</artifactId>
  <version>1.0.0-SNAPSHOT</version>
  <packaging>pom</packaging>
  <modules>
    <module>bundles</module>
  </modules>
</project>

Sadly without luck.
Can you give me hint how to specify the additional domain1 feature / bundles?
I have a sample repo where I try to evaluate.

In any case its good to explain what you expected and what you get instead.

It complains that it can't find a "root" pom in your domain1 folder, so you can place a pom there or configure the path to the parent:

I added the file structure and my current understanding into the README.
currently I get the error Project 'example.rcp:bundles:1.0.0-SNAPSHOT' is duplicated in the reactor
So my question are

• what to specifiy in the top level parent pom.xml for the domain1 sub-folder
• is a "connector" domain1/pom.xml required?
• is the domain1/bundles-b1/build.properties specified tycho.pomless.parent = ../../.. and correct?

[laeubi]

You can place a build properties file in the domain1/bundles folder and there configure the parent and a different module name (so you don't need this in each individual bundle!):

Thx for help. Finallly I got.
I updated the wiki page to make it more detailed for slow guys like myself :-) Hope that is fine with you.

In my experience, if you have a pom-less Tycho build, and you use non-default folder names in the root of your repo, that contain your plugins/features/etc, you need to run Maven with -Dtycho.pomless.aggregator.names=folder1,folder2,folder3 to make Maven/Tycho aware of this. Just adding them as modules to pom.xml is not enough. See also this example.

[laeubi]

@dhendriks this is only required if you use non "standard" names, what is not the case here.

[dhendriks]

The different folders for specific domains containing feature / bundle sets part of the original question made me think that indeed non-standard names are being used.
