Bootable JAR - Second bootable JAR fails to package if first uses certain layers -------------------------------------------------------------------------------- Key: WFWIP-346 URL: https://issues.redhat.com/browse/WFWIP-346 Project: WildFly WIP Issue Type: Bug Reporter: Jan Kasik Assignee: Jean Francois Denise Priority: Critical See the reproducer: https://github.com/honza-kasik/layer-conflict - there are two Maven modules, each configured to run WildFly Maven JAR plugin. If I run {{mvn clean package -Dversion.org.wildfly.jar.plugin=2.0.0.Beta3}}, bootable JAR for app-one builds but for app-two the build ends up with an error and app-two fails to package: {noformat} [ERROR] Failed to execute goal org.wildfly.plugins:wildfly-jar-maven-plugin:2.0.0.Beta3:package (default) on project app-two: Provisioning failed: Failed to generate standalone.xml on { [ERROR] "operation" => "composite", [ERROR] "address" => [], [ERROR] "rollback-on-runtime-failure" => true, [ERROR] "steps" => [ [ERROR] { [ERROR] "operation" => "add", [ERROR] "address" => [("interface" => "public")], [ERROR] "inet-address" => "${jboss.bind.address:127.0.0.1}" [ERROR] }, [ERROR] { [ERROR] "operation" => "add", [ERROR] "address" => [("extension" => "org.wildfly.extension.bean-validation")] [ERROR] }, [ERROR] { [ERROR] "operation" => "add", [ERROR] "address" => [("extension" => "org.jboss.as.weld")] [ERROR] }, [ERROR] { [ERROR] "operation" => "add", [ERROR] "address" => [("extension" => "org.jboss.as.naming")] [ERROR] }, [ERROR] { [ERROR] "operation" => "add", [ERROR] "address" => [("extension" => "org.jboss.as.ee")] [ERROR] }, [ERROR] { [ERROR] "operation" => "add", [ERROR] "address" => [("extension" => "org.wildfly.extension.io")] [ERROR] }, [ERROR] { [ERROR] "operation" => "add", [ERROR] "address" => [("extension" => "org.wildfly.extension.undertow")] [ERROR] }, [ERROR] { [ERROR] "operation" => "add", [ERROR] "address" => [("extension" => "org.jboss.as.jaxrs")] [ERROR] } [ERROR] ] [ERROR] }: {"WFLYCTL0062: Composite operation failed and was rolled back.
