Unresolveable build extension while resolving grails plugins using maven - maven

Question

I am trying to compile a grails project using maven. I am getting the following error
[INFO] Scanning for projects...
[WARNING] The POM for org.grails.plugins:kickstart-with-bootstrap:jar:1.1.0 is missing, no dependency information available
[ERROR] The build could not read 1 project -> [Help 1]

The error is such that I am not even able to generate the dependency tree. I am attaching my pom.xml. Could anyone please tell me where I am going wrong.

Answer 1

You have 2 implementations incorrect here:
kickstart-with-bootstrap is a grails plugin dependency therefore it should be under <dependencies> section in pom.xml, instead of a maven plugin.
Grails plugins are packaged as zip and not jar, so the <type> of dependency should be zip
Solution:
Remove this section
<plugin>
<groupId>org.grails.plugins</groupId>
<artifactId>kickstart-with-bootstrap</artifactId>
<version>1.1.0</version>
<configuration>
<grailsVersion>${grails.version}</grailsVersion>
</configuration>
<extensions>true</extensions>
</plugin>
and add this section under <dependencies>
<dependency>
<groupId>org.grails.plugins</groupId>
<artifactId>kickstart-with-bootstrap</artifactId>
<version>1.1.0</version>
<type>zip</zip>
</dependency>
