Installation

From binaries

Preliminary binary artifacts for ORT are currently available via JitPack. Please note that due to limitations with the JitPack build environment, the reporter is not able to create the Web App report.

From sources

Install the following basic prerequisites:

  • Git (any recent version will do).

Then clone this repository.

git clone https://github.com/oss-review-toolkit/ort
# If you intend to run tests, you have to clone the submodules too.
cd ort
git submodule update --init --recursive

Build using Docker

Install the following basic prerequisites:

  • Docker 18.09 or later (and ensure its daemon is running).
  • Enable BuildKit for Docker.

Change into the directory with ORT's source code and run docker build -t ort .. Alternatively, use the script at scripts/docker_build.sh which also sets the ORT version from the Git revision.

Build natively

Install these additional prerequisites:

  • Java Development Kit (JDK) version 11 or later; also remember to set the JAVA_HOME environment variable accordingly.

Change into the directory with ORT's source code and run ./gradlew installDist (on the first run this will bootstrap Gradle and download all required dependencies).

Basic usage

Depending on how ORT was installed, it can be run in the following ways:

  • If the Docker image was built, use

    docker run ort --help

    You can find further hints for using ORT with Docker in the documentation.

  • If the ORT distribution was built from sources, use

    ./cli/build/install/ort/bin/ort --help

  • If running directly from sources via Gradle, use

    ./gradlew cli:run --args="--help"

    Note that in this case the working directory used by ORT is that of the cli project, not the directory gradlew is located in (see gradle/gradle#6074).

For simplicity of the following usage examples, the above ORT invocations are unified to just ort --help.
