[shrinkwrap-issues] [JBoss JIRA] (SHRINKDESC-120) Confusing exception when filename string passed to DescriptorImporter.from(...)

Confusing exception when filename string passed to DescriptorImporter.from(...) ------------------------------------------------------------------------------- Key: SHRINKDESC-120 URL: https://issues.jboss.org/browse/SHRINKDESC-120 Project: ShrinkWrap Descriptors Issue Type: Task Components: api Reporter: Craig Ringer Assignee: Andrew Rubinger Fix For: 2.0.0-alpha-3 Descriptors 2.0.0.alpha2 It's too easy to write: {code} BeansDescriptor beansXml = Descriptors.importAs(BeansDescriptor.class) .from("src/main/webapp/WEB-INF/beans.xml"); {code} when you really meant: {code} BeansDescriptor beansXml = Descriptors.importAs(BeansDescriptor.class) .from(new File("src/main/webapp/WEB-INF/beans.xml")); {code} The incorrect code reads fine, and the exception thrown doesn't make it at all obvious what's happening: {code} java.lang.RuntimeException: Could not invoke deployment method: public static org.jboss.shrinkwrap.api.spec.JavaArchive com.example.shrinkwraptestsk eleton.DemoTest.createDeployment() .... Caused by: java.lang.reflect.InvocationTargetException .... Caused by: org.jboss.shrinkwrap.descriptor.api.DescriptorImportException: Could not import XML from stream .... Caused by: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog. .... {code} I'd like to replace ".from(String)" with ".fromString(...)" . The unqualified .from() could continue to accept an InputStream or Reader, just not String. Adding ".fromFile(String)" is probably pointless given it'd be a pointless wrapper around "new File(..)".
