Building Apache Taverna¶
You need Apache Maven 3.2 or newer to build Taverna. To build a checked out repository:
mvn clean install
If you want to skip tests (these can be time-consuming):
mvn clean install -DskipTests
If you get license header warnings from the Apache RAT plugin, and you are not a committer (who should fix those before a release), you can skip these checks with:
mvn clean install -Drat.skip=true
The build order is roughly the order of the above list, but as regular
snapshots are picked up from the snapshot repository,
usually you only need to build the modules you have changed.
Note that a repository might depend on a released version of an upstream Taverna
repository, so if you want to be sure that a build picks up the
you built instead, check the
<properties> section within the
Contribute to Apache Taverna¶
Patches welcome! Apache Taverna is a volunteer project, and we rely on the community to help improve the code base. Anyone can suggest a change to Apache Taverna, not just the existing committers.
For many developers, the easiest method is to Fork the corresponding repository on GitHub, and submit the suggested changes as a Pull request. The pull request is automatically forwarded to the dev@taverna mailing list. Subscribe to this mailing list to receive feedback for your patch.
Alternatively, you may checkout directly from the repositories above, use git format-patch, and send your patches to the dev@taverna mailing list after subscribing. Note that large patch files might not be accepted by the mailing list software.
For larger contributions, we might ask you to sign a Contributor License Agreement (CLA) to grant a license to the Apache Software Foundation that covers your contribution.
For any questions about using or modifying the Apache Taverna source code and APIs, please subscribe to and contact the dev@taverna mailing list.
Use the Apache Taverna JIRA issue tracker to report or track a bug.
Note that the snapshot builds are not official releases and should be considered unstable.
To use the snapshot repository, add to your Maven pom.xml:
<repositories> <repository> <id>apache.snapshots</id> <name>Apache Snapshot Repository</name> <url>http://repository.apache.org/snapshots</url> <releases> <enabled>false</enabled> </releases> </repository> </repositories>
This means that as a developer, you only need to build the repositories you are modifying, as the remaining modules will be retrieved from the Maven repository.
You will however always need to build the distribution product (command line or workbench) to incorporate your changes. (Make sure that references the correct
The separate GitHub group taverna-extras host independent community-submitted plugins for Apache Taverna. Unlike Apache Taverna, the taverna-extras include plugins covered by the licenses LGPL and GPL. Note that the taverna-extras are not affiliated with or released by Apache Taverna, although you may recognize many of the same committers.
Some plugins that were previously part of Taverna 2 have or will migrate to taverna-extras due to licensing incompatibility. This includes:
- RShell activity
- Table activity
