Resource nexus-maven-repository-index.properties does not exist in IntelliJ

问题

While experimenting with Grails 3 under IntelliJ I found the following warning:

 Unindexed remote maven repositories found. Disable...
 The following repositories used in your gradle projects were not indexed yet: 
 https://repo.grails.org/grails/core
 If you want to use dependency completion for these repositories artifacts,
 Open Repositories List, select required repositories and press "Update" button (show balloon)

If I am trying to resolve an issue, I get next error:

FileNotFoundException: Resource nexus-maven-repository-index.properties does not exist in IntelliJ

I would prefer to know, what does it mean? If repository is marked as "remote", then why the problem is absence of some (local?) file?

UPDATE

I think this is not related with Grails actually.

How to know more details on error, occurring in Indexed Maven Repositories Window in IntelliJ on Update button?

The popup message says

Resource nexus-maven-repository-index.properties does not exist in IntelliJ

回答1:

If you're using your custom repository
AND it is Nexus 3.x

chances are high that you forgot to set up a Task to publish your maven repository indexes.

Set it for an hourly publish. Done.

For me the solution was to delete the folder ~/.m2/repository. This made Maven to re-index everything correctly.

Failed trials, that may work for someone else:

Build, Execution, Deployment → Build Tools → Maven → Repositories : Selecting the repositories and click updates.
Build, Execution, Deployment → Build Tools → Maven: Giving more memory JVM
Delete folder ~/.IntelliJIdea2016.3/system/caches

You can try using grails/repo and grails/plugins instead of grails/core.

For example, in build.gradle:

repositories {
    mavenLocal()
    maven { url 'http://repo.grails.org/grails/repo' }
    maven { url 'http://repo.grails.org/grails/plugins' }
}

I tested on IntelliJ Community 15 with Grails 3.0.9, JVM Version: 1.8.0_45, Apache Maven 3.3.9 and Gradle 2.3.

The same error occurs for Artifactory users. Solved with sanya's hint. Make sure the local repositories are included.

After that the repo works:
