Hi,
I encounter the missing POM issue for wstx-asl and selenium-server-standalone while building default branch via maven.
Just fixing it by applied below changes
1. org.idempiere.fitnesse.server/pom.xml
<artifactItem>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-server-standalone</artifactId>
<version>2.53.0</version>
</artifactItem>
change version to 2.53.0
2. org.adempiere.server-feature/pom.xml
<artifactItem>
<groupId>org.codehaus.woodstox</groupId>
<artifactId>wstx-asl</artifactId>
<version>3.2.7</version>
</artifactItem>
change groupId to org.codehaus.woodstox.
After those changes, it is able to find .pom file from maven repository.
Hope it helps someone if having same issue.
BR,
Ken
