#Diffinery plugin for JetBrains IDEs

Adds Diffinery to Get from Version Control in IntelliJ IDEA, PyCharm, WebStorm, GoLand and the other JetBrains IDEs (2024.3 and later), with the browser sign-in Diffinery's other apps use (OAuth with PKCE on a 127.0.0.1 redirect, client /oauth/clients/jetbrains.json). Git asks the plugin for the password when it talks to the server, and Git → Share Project on Diffinery… publishes a local repository. The guide people read is Clone in JetBrains IDEs.

It's plain Java (no Kotlin), against the platform's stable API only: ./gradlew verifyPlugin runs JetBrains' Plugin Verifier against IntelliJ IDEA 2024.3, 2025.2 and the version the plugin builds with, and fails on internal API use.

#Build

Gradle 9 through the wrapper, with a JDK 21 or later (the IDE's own JetBrains Runtime works):

./gradlew dist        # builds and copies the plugin to dist/diffinery-jetbrains-<version>.zip
./gradlew test        # unit tests
./gradlew verifyPlugin

-PideaHome=/path/to/idea builds against an IDE already on disk instead of downloading IntelliJ IDEA, and -Porg.gradle.java.installations.paths=/path/to/idea/jbr uses its runtime as the JDK.

#How diffinery.com serves it

dist/ is checked in, because Diffinery's server build has no JDK. apps/diffinery/scripts/build-docs.mjs reads it through scripts/plugin.mjs, which refuses a zip whose version isn't pluginVersion in gradle.properties or that was built from other sources than src/main now (the build puts a fingerprint of them in the jar). So after changing the plugin, run ./gradlew dist and commit the new zip with the change; the zip is byte-for-byte reproducible.

The Worker serves:

#Release

1. Bump pluginVersion in gradle.properties and add a CHANGELOG.md entry.
2. ./gradlew test verifyPlugin dist, then run the real-IDE check (below).
3. Commit with the new dist/ zip. Once deployed, IDEs with the plugin repository offer the update.

#Real-IDE check

apps/diffinery/test/e2e/jetbrains-smoke.mjs drives IntelliJ IDEA against a local Worker through JetBrains' Remote Robot server: it installs the plugin from the Worker's plugin repository in Settings → Plugins, signs in through the consent page in Chromium, lists, searches and clones a private repository, shares a project, signs out, and signs in with a token. See the comment at its top for how to run it. DOCS=1 retakes the pictures in the guide.

Publishing on the JetBrains Marketplace waits until Diffinery is public: see PUBLISHING.md.
