Troubleshooting

List of changes is empty

By default, you will only see changes to Git repositories that are configured in the current project of your IntelliJ IDE.

• Make sure that Git repositories are configured in the 'Version Control' settings.
• Make sure that the Git repository remote url (at least one of them) is on the same host as configured in Gerrit plugin settings. Or:
• Set the 'Clone Base URL' if it differs from the Gerrit web url. Or:
• Add a remote whose name equals the Gerrit project name with Gerrit web url as remote url.

Error-message when clicking a change: "VcsException: fatal: bad object"

In Gerrit 2.8, fetch information was pulled out of default functionality into a plugin. You need to install the plugin download-commands. When you run the Gerrit update procedure, it asks you to install this plugin (but it isn't selected by default). Just run the update script again if you have not installed it yet.

When installing Gerrit 2.8 (or newer) from scratch (rather than using the update script) the following command will install the download-commands plugin (for a new installation or an existing Gerrit instance):

$ java -jar gerrit.war init -d {gerrit-instance} --install-plugin=download-commands

Error-message when loading changes: "SSLException: Received fatal alert: bad_record_mac"

There are two workarounds for this issue:

• allow TLSv1 (instead of SSLv3 only) connections in your reverse-proxy in front of Gerrit. SSLv3 is considered insecure, therefore TLS should be the default in any case.
• use a recent Java setup (> 1.6)

Error-message when loading changes: "Bad Request. Status-Code: 400. Content: too many terms in query."

Open plugin settings and enable the option "List all Gerrit changes (instead of changes from currently open project only)".

Checking out from VCS with Gerrit plugin does not work

Checking out directly with the Gerrit plugin does not work for some authentication methods. If you get an authentication error or checking out does not properly finish, you can try to:

• use SSH clone URL in checkout dialog (you can find the SSH URL in the Gerrit Web UI project settings)
• or: check out with the default Git plugin and set up the Gerrit plugin manually afterwards

You can find background information about this issue in a Gerrit mailing list topic.

Loading file-diff-list is slow

Diff viewing is based on Git operations (i.e. it fetches the commit from the Gerrit remote). When loading the file list takes a lot of time, you can run a local "git gc" and ask your Gerrit administrator to do run a "gerrit gc".

Authenticate against *-review.googlesource.com

It's a bit of manual work to do: Settings -> HTTP Credentials -> Obtain password

Then search for the line in the text area starting with *-review.googlesource.com (e.g. gerrit-review.googlesource.com) and extract username and password:

gerrit-review.googlesource.com,FALSE,/,TRUE,12345678,o,git-username.gmail.com=password-until-end-of-line

Architecture

IntelliJ Integration

The plugin is integrated into the IntelliJ IDE with a tool window. See package com.urswolfer.intellij.plugin.gerrit.ui.

REST API

Most of the communication between the plugin and a Gerrit instance is based on the Gerrit REST API. The REST specific part is available as standalone implementation. See package com.urswolfer.intellij.plugin.gerrit.rest.

Git

Some actions like comparing and listing files are based on Git operations. IntelliJ Git4Idea is used for these operations. See package com.urswolfer.intellij.plugin.gerrit.git.

Build (and develop!) the Plugin

It's very easy to set it up as an IntelliJ project.

1. Activate plugins Gradle, Plugin DevKit and UI Designer in IntelliJ.
2. git clone https://github.com/uwolfer/gerrit-intellij-plugin (probably switch to intellij{version} branch, but keep in mind that pull-requests should be against the default branch ("intellij13" and older are not supported anymore))
3. Open checked out project in IntelliJ ("File" -> "New" -> "Project from Existing Sources" -> select file build.gradle in gerrit-intellij-plugin folder and press "OK")
4. Create a new run configuration: "Gradle" -> "Gradle project": select the only project -> "Tasks": "runIde"
5. Press "Debug" button. IntelliJ should start with a clean workspace (development sandbox). You need to checkout a project to see changes (it shows only changes for Git repositories that are set up in current workspace by default).

Once build.gradle gets updated, you need to "Refresh all Gradle projects" in the Gradle panel.
