Configuring compiler settings

IntelliJ IDEA 12

JetBrains IDEA 12.0 has a new compiler feature named "external build", which is enabled by default in project settings (File > Settings > Project Settings > Compiler > "Use external build" toggle). The IDEA 12 is supported since Clover version 3.1.8, however the support for "external build" feature is available since Clover version 3.1.12 and IDEA 12.1.1. For older versions, i.e. the combination of Clover 3.1.8-3.1.12 and IDEA 12.0.0-12.1.0 please keep the "external build" feature disabled.

IntelliJ IDEA 13

In the IDEA 13.0 the "external build" feature has become default setting and thus there's no 'Use external build' toggle available.

Enabling the "external build" feature

Open the File > Settings > Project Settings > Compiler page.


Use the following state for toggles:

  • Use external build - it can be either enabled (the new IDEA12 feature is used) or disabled (the "classic" IDEA build is used)
  • Make project automatically - it's strongly recommended to disable this option; enabling it causes frequent compilation and faster growth of Clover database, which might affect performance
  • Compile independent modules in parallel - it must be disabled; Clover does not support parallel build; follow the CLOV-1293 for future updates

Known Issues

  • If you are using the Maven build tool, you should avoid using the same IntelliJ output directory as Maven does. As Maven uses the target/classes and target/test-classes directories, avoid specifying these ones. The clover.db location for IntelliJ should also be distinct from that used by Maven.

Uninstalling the Plugin

The easiest way to uninstall it is via 'File > Settings > Plugins' (Linux, Windows) or 'IDEA > Preferences > Plugins' (OS X). Just select the Clover IDEA Plugin from the list and click 'Uninstall Plugin'. The removal will take place after you restart IDEA.

To uninstall Clover-for-IDEA manually:

  1. Shut down any running instances of IDEA.
  2. Delete the 'clover-idea.jar' file from its installation directory, either IDEA_HOME/config/plugins (all platforms),  IDEA_HOME/plugins (all platforms except Mac OS X) or USER_HOME/Library/Application\ Support/IntelliJIDEA70 (Mac OS X only)
  3. Restart IDEA.
