Question

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

 Unindexed remote maven repositories found. Disable...
 The following repositorie         


        

Answer 1

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

After that the repo works:

Answer 2

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.

Answer 3

• 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.

Log in via browser. Go to Administration/System/Tasks/Create Task/Create Publish Maven indexes Task

Set it for an hourly publish. Done.

Answer 4

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
