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 Java 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.
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.
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.
