Apache Taverna is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision-making process have stabilized in a manner consistent with other successful ASF projects.

While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.


  • Java 1.8 or newer (tested with OpenJDK 1.8)
  • Apache Maven 3.2.5 or newer (older versions probably also work)

This code relies on other Apache Taverna modules, which Maven shuold automatically download from Apache's Maven repository; however you might want to compile these yourself in the below order:

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 their tests.

Building on Windows

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.

Skipping tests

To skip the tests (these can be time-consuming), use:

mvn clean install -DskipTests

If you are modifying this source code independent of the Apache 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


Each module implement a particular type of Taverna Activity.

Export restrictions

This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org/ for more information.

The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.
