You use this panel to configure Maven settings that affect the behavior of Maven in the IDE.
You can access this panel by choosing Tools > Options from the main menu, clicking the Miscellaneous category and then clicking the Maven tab.
You can specify the following Maven settings:
Maven Home.
By default, the IDE uses the version of Maven that is bundled and installed with the IDE.
To use a different Maven installation, click Browse and specify the location of the local Maven installation
(e.g., /usr/local/maven/apache-maven-209).
Global Execution Options. Click Add to select additional Maven execution
options to apply to all Maven projects.
Local Repository. Click Browse to specify or modify the location of the
local Maven repository if different from the repository specified by the Maven installation.
Dependency Download Strategy.
Use the drop-down list to specify how often the IDE performs the listed tasks when a Maven project is opened.
The default setting for the tasks is Never.
Modifying the setting can have a significant impact on performance
when opening a Maven project.
Edit Global Custom Goal Definitions.
Opens a dialog box where you can configure custom Maven goals
that can be invoked from any Maven project.
You can invoke custom goals by right-clicking the project in the Projects window
and choosing Custom.
Index Update Frequency. Use the drop-down list to specify how often the IDE
checks the remote repository for updates.
Include Snapshots. When selected, indexes of the local repository
include snapshot versions of artifacts.
Note.
If you are using Maven with a proxy host you might need to specify
the proxy settings explicitly in the Maven settings.xml file.
For details about Maven proxy settings, see the following FAQ.
