[ https://issues.jboss.org/browse/JBIDE-14430?page=com.atlassian.jira.plugi... ] Aslak Knutsen commented on JBIDE-14430: --------------------------------------- Sure, you could scan for multiple classes that implement the interface DeploybleContainer, but it might give you false positives. The setup is: {code:title=META-INF/services/org.jboss.arquillian.core.spi.LoadableExtension} MyLoadableExtensionClass {code} {code} class MyLoadableExtensionClass implements LoadableExtension { void build(Builder b) { b.service(DeplyableContianer.class, MyDeployableContianer.class) } } {code} MyLoadableExtensionClass could have logic in it when registrering the DeploybleContainer impls, meaning multiple might be found on classpath, but only one will be active. Another possibility is that an Extension could override the default 'only one container allowed' restriction. -- This message is automatically generated by JIRA.
