[shrinkwrap-issues] [JBoss JIRA] (SHRINKDESC-115) Descriptors 2.0 module creates duplicate <alternatives/> entries (test case attached)

Descriptors 2.0 module creates duplicate <alternatives/> entries (test case attached) ------------------------------------------------------------------------------------- Key: SHRINKDESC-115 URL: https://issues.jboss.org/browse/SHRINKDESC-115 Project: ShrinkWrap Descriptors Issue Type: Bug Environment: java version "1.7.0_01" Java(TM) SE Runtime Environment (build 1.7.0_01-b08) Java HotSpot(TM) 64-Bit Server VM (build 21.1-b02, mixed mode) Linux ayaki.localdomain 3.3.0-4.fc16.x86_64 #1 SMP Tue Mar 20 18:05:40 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Reporter: Craig Ringer Assignee: Ralf Battenfeld Labels: alternative, arquillian, beans, beans.xml, descriptors, shrinkwrap Attachments: ArquillianShrinkwrapDuplicateAlternatives.zip Using: org.jboss.shrinkwrap.descriptors:shrinkwrap-descriptors-impl-javaee:jar:2.0.0-alpha-2 The attached test case produces an invalid beans.xml with a duplicate <alternatives/> entry with the code: {code} BeansDescriptor beansXml = Descriptors.importAs(BeansDescriptor.class) .from(new File("src/main/webapp/WEB-INF/beans.xml")) .getOrCreateAlternatives(); {code} 'getOrCreate' is in fact always creating an alternatives entry, so the following beans.xml is produced in the example: {code} <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd"> <alternatives> <alternative>com.example.shrinkwraptestskeleton.Production</alternative> </alternatives> <alternatives/> </beans> {code} The produced beans.xml descriptor fails at deployment time with: org.jboss.weld.exceptions.DefinitionException: WELD-001203 <alternatives> can only be specified once, but appears multiple times: vfs:/content/demo.jar/META-INF/beans.xml@6 Also: Since there can only ever be one <alternatives/> block, it's not clear what the difference between getOrCreateAlternatives() and createAlternatives() is. Is the latter supposed to *replace* any existing block? The API for managing alternatives is in Descriptors 2.0 is IMO difficult to use and understand. Issues with examples pending.
