Cromwell Releases

Cromwell releases are available at the GitHub Releases page. You are strongly encouraged to use the latest release of Cromwell whenever possible.

Cromwell is distributed as a conda package on conda-forge. These instructions need to be followed for installing the miniconda distribution and activating the conda-forge channel. After this Cromwell can be installed in the base environment with conda install cromwell or a separate environment for Cromwell can be created with conda create -n cromwell cromwell. If you are using Cromwell for bioinformatics workflows, you might like to take a look at bioconda as well. The conda installation of Cromwell comes with a wrapper that locates the jar for you and allows for running Cromwell or Womtool with a cromwell run, womtool validate or other command. Conda also installs the required Java dependency in the environment automatically.

Mac users with Homebrew can also get Cromwell with the command brew install cromwell.

This documentation frequently refers to a "Cromwell jar" with a name like cromwell-<version>.jar. This is the main artifact in Cromwell releases that contains all executable Cromwell code and default configuration.

Java 8 is required to run Cromwell.

For users running a cromwell server a docker image has been made available.
