tl;dr: The Taverna code base is no longer maintained and is provided here for archival purposes.
In 2020 the Taverna community voted to retire Taverna as a project and withdraw the code base from the Apache Software Foundation.
This code base remains available under the Apache License 2.0 (see License below), but is now simply called Taverna rather than
Apache Taverna (incubating).
While the code base is no longer actively maintained, Pull Requests are welcome to the GitHub organization taverna, which may infrequently be considered by remaining volunteer caretakers.
Releases 2015-2018 during incubation at Apache Software Foundation are available from the ASF Download Archive https://archive.apache.org/dist/incubator/taverna/
Releases 2014 from the University of Manchester are on BitBucket https://bitbucket.org/taverna/
Releases 2009-2013 from myGrid are on LaunchPad https://launchpad.net/taverna/
Releases 2003-2009 are on SourceForge https://sourceforge.net/projects/taverna/files/taverna/
Binary JARs for Taverna are available from Maven Central https://repo.maven.apache.org/maven2/org/apache/taverna/ or the myGrid Maven repository https://repository.mygrid.org.uk/
Taverna Command-line Tool provides a shell command for executing Taverna workflows, defined using either the Taverna Language API in the SCUFL2
.wfbundle format, or in the
.t2flow format from Taverna Workbench 2.5.
Workflow inputs can be provided as parameters or files, while outputs can be saved either to a folder or a Research Object bundle including detailed provenance, which can be inspected using Taverna Language's DataBundle support.
Note that, except for command-line handling, this module relies on other Taverna components for the actual workflow execution.
This product includes software developed at The Apache Software Foundation.
The file NOTICE contains any additional attributions and details about embedded third-party libraries and source code.
Taverna Command-line Tool product relies on other Taverna components which have their own source code repositories.

Please see the
<properties> of this pom.xml to find the correct versions to build.
To build, use
mvn clean install
This will build each module and run its tests.
Note that this repository relies on other Taverna modules which will be downloaded from Maven repositories if they are not already present in the equivalent of your
~/.m2/repository in the correct version.
If you are building on Windows, ensure you unpack this source code to a folder with a short path name lenght, e.g.
C:\src - as Windows has a limitation on the total path length which might otherwise prevent this code from building successfully.
To skip the tests (these can be time-consuming), use:
mvn clean install -DskipTests
If you are modifying this source code independent of the Taverna project, you may not want to run the Rat Maven plugin that enforces Apache headers in every source file - to disable it, try:
mvn clean install -Drat.skip=true
If you are building a non-released version of this repository, (e.g. the
pom.xml declares a
-SNAPSHOT version), then Maven might download unreleased snapshot builds for other
-SNAPSHOT Taverna dependencies.
If you are developing one of the Taverna modules and want to test it with the Taverna Command-line Tool, make sure you build it locally first with
mvn clean install to avoid downloading it from the snapshot repository.
Then check that the the
<properties> section of the
pom.xml matches the
<version> of the module you are developing. See also
taverna-commandline-product/pom.xml to hard-code versions of other dependencies.
The default SNAPSHOT update policy for
mvn is daily - you can modify this behaviour with
To build a binary distribution ZIP file that includes third-party dependencies as JAR files, build with the
-Prelease option, which would make
taverna-commandline-product/target/apache-taverna-commandline-3.1.0-incubating-release.zip or equivalent.
After building, see the file
target/maven-shared-archive-resources/META-INF/DEPENDENCIES for details of the licenses of the third-party dependencies. All dependencies should be compatible with Apache License 2.0.
After building, see the
taverna-commandline-product/target directory. Inside you should find a folder like
apache-taverna-commandline-3.1.0-incubating/ which contains the built Taverna Command-line Tool product.
If you prefer a ZIP file, then instead build with the Maven
-Prelease option. You can then unzip at a location of your choice.
If you are running on Windows you may need to put Taverna Command-line Tool in a folder high in the disk hierarchy (e.g.
C:\Taverna), this helps avoid problems with Windows path-length restrictions.
