The purpose of this article is to share with you what happens when IntelliJ IDEA is slow to create Maven projects. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

IntelliJ IDEA is slow to create a maven project, even stuck.

Reason

According to the nature of maven archetype, IDEA actually executes the mvn archetype:generate command, which needs to specify an archetype-catalog.xml file when it is executed.

The parameter to this command is-DarchetypeCatalog. Available values are: remote,internal, local, etc., which is used to specify where to get the archetype-catalog.xml file.

Remote-- points to Catalog of Maven Central Warehouse

Internal--maven-archetype-plugin built-in

Local to local--, location is ~ / .m2/archetype-catalog.xml

The default is remote, which downloads the archetype-catalog.xml file from the http://repo1.maven.org/maven2/archetype-catalog.xml path.

The http://repo1.maven.org/maven2/archetype-catalog.xml file is about 3-4m, and the download speed is very slow, causing the creation process to get stuck.

Solution one

Add the archetypeCatalog=internal parameter when creating the Maven project, as follows:

Solution two

Add the-DarchetypeCatalog=internal parameter to the VM Options of maven as follows:
