Maven不使用依赖项pom.xml中指定的存储库

Question

Our project depends on drools

<dependency>
  <groupId>org.drools</groupId>
  <artifactId>drools-compiler</artifactId>
  <version>6.1.0.Final</version>
</dependency>

Maven can find drools-compiler in Maven central repository. The problem is that Maven cannot find some dependencies of drools-compiler , which are located in jboss Maven repository http://repository.jboss.org/nexus/content/groups/public/ .

The parent of drools-compiler is drools-multiproject , and it declares jboss repository as follows

<repository>
  <id>jboss-public-repository-group</id>
  <name>JBoss Public Repository Group</name>
  <url>http://repository.jboss.org/nexus/content/groups/public/</url>
  <layout>default</layout>
  <releases>
    <enabled>true</enabled>
    <updatePolicy>never</updatePolicy>
  </releases>
  <snapshots>
    <enabled>true</enabled>
    <updatePolicy>daily</updatePolicy>
  </snapshots>
</repository>

I also checked the effective pom of drools-compiler , and found jboss maven repository is listed.

In theory Maven should use jboss Maven repository to search those dependencies, but sometimes it doesn't.

I don't know whether there other settings affect Maven's behavior.

Thanks

Did you try adding the dependent repository in your POM. Adding dependent repositories transitively is a potential security bug, so probably Maven is using only repositories listed in your POM.
