| = Gerrit Code Review - Eclipse Setup |
| |
| This document is about configuring Gerrit Code Review into an |
| Eclipse workspace for development. |
| |
| Java 8 or later SDK is require |
| |
| [[setup]] |
| == Project Setup |
| |
| In your Eclipse installation's link:https://wiki.eclipse.org/Eclipse.ini[`eclipse.ini`] file, |
| add the following line in the `vmargs` section: |
| |
| ---- |
| -DmaxCompiledUnitsAtOnce=10000 |
| ---- |
| |
| Without this setting, annotation processing does not work reliably and the |
| build is likely to fail with errors like: |
| |
| ---- |
| Could not write generated class ... javax.annotation.processing.FilerException: Source file already created |
| ---- |
| |
| and |
| |
| ---- |
| AutoAnnotation_Commands_named cannot be resolved to a type |
| ---- |
| |
| First, generate the Eclipse project by running the `tools/eclipse/project.py` script. |
| Then, in Eclipse, choose 'Import existing project' and select the `gerrit` project |
| from the current working directory. |
| |
| Expand the `gerrit` project, right-click on the `eclipse-out` folder, select |
| 'Properties', and then under 'Attributes' check 'Derived'. |
| |
| Note that if you make any changes in the project configuration |
| that get saved to the `.project` file, for example adding Resource |
| Filters on a folder, they will be overwritten the next time you run |
| `tools/eclipse/project.py`. |
| |
| === Eclipse project with custom plugins === |
| |
| To add custom plugins to the eclipse project add them to `tools/bzl/plugins.bzl` |
| the same way you would when |
| link:dev-build-plugins.html#_bundle_custom_plugin_in_release_war[bundling in release.war] |
| and run `tools/eclipse/project.py`. |
| |
| [[Newer Java versions]] |
| |
| Java 9 and later are supported, but some adjustments must be done, because |
| Java 8 is still the default: |
| |
| * Add JRE, e.g.: directory: /usr/lib64/jvm/java-9-openjdk, name: java-9-openjdk-9 |
| * Change execution environemnt for gerrit project to: JavaSE-9 (java-9-openjdk-9) |
| * Check that compiler compliance level in gerrit project is set to: 9 |
| |
| [[Formatting]] |
| == Code Formatter Settings |
| |
| To format source code, Gerrit uses the |
| link:https://github.com/google/google-java-format[`google-java-format`] |
| tool (version 1.7), which automatically formats code to follow the |
| style guide. See link:dev-contributing.html#style[Code Style] for the |
| instruction how to set up command line tool that uses this formatter. |
| The Eclipse plugin is provided that allows to format with the same |
| formatter from within the Eclipse IDE. See |
| link:https://github.com/google/google-java-format#eclipse[Eclipse plugin] |
| for details how to install it. It's important to use the same plugin version |
| as the `google-java-format` script. |
| |
| == Site Initialization |
| |
| Build once on the command line with |
| link:dev-bazel.html#build[Bazel] and then follow |
| link:dev-readme.html#init[Site Initialization] in the |
| Developer Setup guide to configure a local site for testing. |
| |
| |
| == Testing |
| |
| === Running the Daemon |
| |
| Duplicate the existing launch configuration: |
| |
| * In Eclipse select Run -> Debug Configurations ... |
| * Java Application -> `gerrit_daemon` |
| * Right click, Duplicate |
| * Modify the name to be unique. |
| * Switch to Arguments tab. |
| * Edit the `-d` program argument flag to match the path used during |
| 'init'. The template launch configuration resolves to `../gerrit_testsite` |
| since that is what the documentation recommends. |
| |
| * Switch to Common tab. |
| * Change Save as to be Local file. |
| * Close the Debug Configurations dialog and save the changes when prompted. |
