imhotep_pmd

An Imhotep plugin for PMD, the static analyzer.

PMD talks to Imhotep via the Static Analysis Results Interchange Format (sarif), which is simply a JSON with a specific schema.

Installation

1. Install Imhotep itself from PyPI, since imhotep_pmd is merely a binding/plugin for Imhotep:

   pip install imhotep

2. Install imhotep_pmd from PyPI:

   pip install imhotep_pmd

3. Install PMD. Please refer to their website for instructions.

Unless you've unzipped the PMD archive file to ~/bin/pmd-bin-6.44.0/, you'll have to tell imhotep_pmd where to find the executable. This can be achieved by providing a imhotep_pmd.toml at the root directory of the repo you want to run PMD against. The file should contain this line that specifies the command used to invoke PMD:

pmd_command = "~/bin/pmd-bin-6.44.0/bin/run.sh pmd"

Usage

To use the plugin, you'll have to pass a path to the linter in question to the imhotep runtime.

imhotep --linter imhotep_pmd.plugin:PmdLinter

Demo

Let's take #1 as an example.

$ imhotep \
   --repo_name="tslmy/imhotep_pmd" \
   --github-username="tslmy" \
   --github-password="$GITHUB_PASSWORD" \
   --pr-number=1 \
   --linter imhotep_pmd.plugin:PmdLinter

Integrate with Jenkins

This section walks you through the process of setting up a Jenkins job that automatically run PMD and post review comments to new pull requests (PRs) in a specific GitHub repository.

1. Install the Jenkins plugin GitHub Pull Request Builder:
2. In GitHub, create a personal access token (PAT):
3. In Jenkins, create a freestyle project:
4. Under General, tick This project is parameterized, and then add these parameters:
5. Under Source Code Management, tick Git, and then configure it like this:
6. Under Build Triggers, tick GitHub Pull Request Builder, and then configure it your way.
7. Under Build Environment, map your GitHub PAT to the environment variable GITHUB_PASSWORD: If you haven't, you can add the credential to Jenkins like this:
8. Under Build, add a step Execute shell. Populate it with the content of jenkins.sh.
9. Your Jenkins jobs should now automatically run PMD and post review comments whenever a PR is opened.
