Question

Migrating Drools from 6.5.0.Final to Drools 7.36.1.Final , I am facing issue in resolving org.kie:kie-maven-plugin:7.36.0.Final dependency issue as below

[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] Unresolveable build extension: Plugin org.kie:kie-maven-plugin:7.36.0.Final or one of its dependencies could not be resolved: The following artifacts could not be resolved: xmlpull:xmlpull:jar:1.2.0, xpp3:xpp3_min:jar:1.2.0: Could not find artifact xmlpull:xmlpull:jar:1.2.0

POM entry

  <plugin>
    <groupId>org.kie</groupId>
    <artifactId>kie-maven-plugin</artifactId>
    <version>7.36.1.Final</version>
     <extensions>true</extensions>         
 </plugin>

Answer 1

It can be found at: https://mvnrepository.com/artifact/xmlpull/xmlpull/1.2.0. I have no clue why it is not listed here: https://mvnrepository.com/artifact/xmlpull/xmlpull so maven can resolve it.

you can download it and put it into your local m2 repository or into your company maven repository like nexus or artifactory.

Answer 2

You need to add one of those repo-s in your build, so maven can find it:

• https://mvnrepository.com/repos/jboss-ea
• https://mvnrepository.com/repos/jboss-thirdparty-releases

Answer 3

Hi same problem with versions higher than 7.31. Since they changed the dependencies in kie-parent.pom from

<version.xmlpull>1.1.3.1</version.xmlpull>
<version.xmlunit>1.3</version.xmlunit>
<version.xpp3>1.1.4c</version.xpp3>

to

<version.xmlpull>1.2.0</version.xmlpull>
<version.xmlunit>1.3</version.xmlunit>
<version.xpp3>${version.xmlpull}</version.xpp3>

I try lot of tricks and can't solve the problem yet. 1.2.0 it's an ea version located in https://repository.jboss.org/nexus/content/repositories/ea/.
