Feature Model Converter
The Model Converter can convert between the Sling Provisioning Model and the Sling Feature Model and back.
For further documentation see: https://github.com/apache/sling-org-apache-sling-feature/blob/master/readme.md
Building
This tool can be built using mvn clean install. For testing purposes these
arguments can be provided:
- test.prov.files.tempdir: test output folder that must exist before the build
- test.prov.no.delete: if no output folder is provided this flag indicates that the files inside the temporary test output folder is not deleted
The CLI Tool
Attention: as of now the CLI tool is only supporting conversions from Provisioning Model to Feature Model.
The tool is distributed with a commodity package containing all is needed
in order to convert Provisioning Models into Feature Model files. It will
launch the ProvisioningToFeature form the shell:
$ unzip -l target/org.apache.sling.feature.modelconverter-1.0.3-SNAPSHOT.zip

once the package is decompressed, open the shell and type:

Usage: pm2fm [-DhV] [-g=<groupId>] -i=<provisioningModelsInputDirectory>

[-a=<addFrameworkProperties>]... [-d=<dropVariables>]...
[-e=<excludeBundles>]... [-r=<runModes>]...
Apache Sling Provisioning Model to Sling Feature Model converter
-a, --addFrameworkProperty=<addFrameworkProperties>
Adds Framework Property to Feature Models. Format:
<Model Name>:<Property Name>=<value> (repeat for more)
-d, --dropVariable=<dropVariables>
Variable (by name) in a Feature Model to be excluded
(repeat for more)
-D, --noProvisioningModelName
If flagged then the Provisioning Model Name is not added
-e, --excludeBundle=<excludeBundles>
Bundle and/or Bundle Configuration to be excluded
(repeat for more)

-h, --help Display the usage message
-i, --provisining-input-directory=<provisioningModelsInputDirectory>
The input directory where the Provisioning File are
-n, --name=<name> Sets a General Name for all converted Models. This also
means that the name is placed in the classifier

included by default, repeat for more)

given version from Provisioning Model

to see all the available options; a sample execution could look like:
$sh ./bin/pm2fm
-i $SLING_DEV_HOME/sling-org-apache-sling-starter/src/main/provisioning
-o fm.out
-g "${project.groupId}"
-v "${project.version}"
-V
-n "${project.artifactId}"
-D
-a "launchpad:felix.systempackages.substitution=true"
-a "launchpad:felix.systempackages.calculate.uses=true"
-r ":standalone"
-r "oak_tar"
**Attention**: the current Model Converter is adding runmode bundles and
configurations with a **id** that has a suffix of **.runmode.<runmode name>**
which will not work with the Feature Launcher as the Feature Model does not
support runtime selection / configuration.
The **-r** argument provides the ability to select the desired runmodes which
then does not add the suffix to the id and drop all other runmodes. See
SLING-8479 for more on this.
**Note**: this will generate all the Feature Models for the current Sling
Provisioning (Sling (PM) Starter). The groupId, artifactId and version is
set to a placeholder and with it the model name is placed inside the classifier.
In addition the Provisioning Model Name is dropped (duplicates) and two
framework properties are added to the launchpad FM to make bundles that uses
Java dependencies activate.
Argument Files for Long Command Lines:
argfile to convert Sling Provisioning Model to Feature Model
SLING_DEV_HOME points to the sling development folder
-i $SLING_DEV_HOME/sling-org-apache-sling-starter/src/main/provisioning
Will be created if it does not exists
-o fm.out
Set the Model Id parts and add the name as classifier
-g "${project.groupId}" -v "${project.version}" -n "${project.artifactId}"
Override any existing version number
-V
Delete Provisioning Model Name to avoid duplicates
-D
Add Launchpad Framework Properties to make bundles with Java dependencies activate
-a "launchpad:felix.systempackages.substitution=true" -a "launchpad:felix.systempackages.calculate.uses=true"
Exclude Lauchpad Installer (provided by the feature launcher) and Repository
Initializer as this is embedded in the configuration file
-e "org.apache.sling.launchpad.installer" -e "org.apache.sling.jcr.repoinit.impl.RepositoryInitializer"
This is a build for the standalone OAK Segment Node Store which needs
these two runmodes but we dropped all others like :webapp or oak_mongo
-r "oak_tar" -r ":standalone"
