Infinispan Common Parent POM doesn't follow its schema ------------------------------------------------------ Key: ISPN-3040 URL: https://issues.jboss.org/browse/ISPN-3040 Project: Infinispan Issue Type: Bug Affects Versions: 5.2.5.Final, 5.3.0.Alpha1 Reporter: Vladimir Dosoudil Assignee: Tristan Tarrant Fix For: 5.3.0.Beta1, 5.3.0.Final The POM of Infinispan Common Parent (parent/pom.xml) is invalid against its [schema|http://maven.apache.org/xsd/maven-4.0.0.xsd]: {code} parent/pom.xml:1800: element configuration: Schemas validity error : Element '{http://maven.apache.org/POM/4.0.0}configuration', attribute 'combine.self': The attribute 'combine.self' is not allowed. parent/pom.xml:1851: element configuration: Schemas validity error : Element '{http://maven.apache.org/POM/4.0.0}configuration', attribute 'combine.self': The attribute 'combine.self' is not allowed. {code} The [commit|https://github.com/infinispan/infinispan/commit/1ade18efcfcd73dadb...] for [JBQA-6819|https://issues.jboss.org/browse/JBQA-6819] brings the attribute _combine.self_ for the _configuration_ element. This attribute is not allowed for the _configuration_ element but for its children, see [POM Reference|http://maven.apache.org/pom.html]: {quote} You can control how child POMs inherit configuration from parent POMs by adding attributes *to the children of the configuration element*. The attributes are combine.children and combine.self. Use these attributes in a child POM to control how Maven combines plugin configuration from the parent with the explicit configuration in the child. {quote} Checked on 5.2.x branch but the bug is on both branches 5.2.x and master.
