Common Maven issues

There are two kinds of Maven-related issues commonly seen in the TeamCity build configurations:

• Error message on "Maven" tab of build configuration: "An error occurred during collecting Maven project information ... "

• Error message in build configuration with Maven dependencies trigger activated: "Unable to check for Maven dependency Update ..."

If the build configuration produces successful builds despite displaying such error messages, these errors are likely to be caused by the server-side Maven misconfiguration.

To collect information for the Maven tab, or to perform Maven dependencies check (for the trigger), TeamCity runs the embedded Maven. The execution is performed on the server machine, and any agent-side maven settings are not accessible. TeamCity resolves the settings.xml files on the server-side separately, as described on this documentation page.

It makes sense to check if the server-side settings.xml files contain correct information about remote repositories, proxies, mirrors, profiles, credentials etc.
