Description

It seems that `go-offline` goal does not download dependencies which are declared as plugin dependency:

e.g

<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>groovy-maven-plugin</artifactId>
<version>${groovy-maven-plugin.version}</version>
<dependencies>
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-all</artifactId>
<version>3.0.9</version>
<type>pom</type>
<exclusions>
<exclusion>
<!-- groovy-testng depends on testng 7.2.0 wich is not on maven central -->
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-testng</artifactId>
</exclusion>
</exclusions>
</dependency>
</dependencies>
</plugin>

After org.apache.maven.plugins:maven-dependency-plugin:3.3.0:go-offline I still get:

[ERROR] Failed to execute goal org.codehaus.gmaven:groovy-maven-plugin:2.1.1:execute (set-platform-properties) on project mvnd: Execution set-platform-properties of goal org.codehaus.gmaven:groovy-maven-plugin:2.1.1:execute failed: Plugin org.codehaus.gmaven:groovy-maven-plugin:2.1.1 or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.codehaus.groovy:groovy-all:pom:3.0.9, org.codehaus.plexus:plexus-utils:jar:1.1: Cannot access central ([https://repo.maven.apache.org/maven2]) in offline mode and the artifact org.codehaus.groovy:groovy-all:pom:3.0.9 has not been downloaded from it before. -> [Help 1]

How to reproduce

git clone https://github.com/apache/maven-mvnd.git
git checkout 0.8.0
mvn org.apache.maven.plugins:maven-dependency-plugin:3.3.0:go-offline -Pnative -Dmaven.repo.local=/tmp/m2
mvn -o verify -Pnative -Dmaven.repo.local=/tmp/m2
