Say I have a very simple Java program using the WildFly CLI scripting facilities:
public static void main(String[] args) throws Exception { CLI cli = CLI.newInstance(); cli.connect(); System.out.println(cli.cmd(":whoami").getResponse()); cli.disconnect(); }
This is in a small Maven project that has a single dependency:
<dependency> <groupId>org.wildfly.core</groupId> <artifactId>wildfly-cli</artifactId> <version>2.1.0.Final</version> </dependency>
When trying to run the program (no matter if there's a running WildFly server or not), I get the following exception:
Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss/logmanager/LogContextSelector at org.jboss.as.cli.embedded.EmbeddedControllerHandlerRegistrar.registerEmbeddedCommands(EmbeddedControllerHandlerRegistrar.java:89) at org.jboss.as.cli.impl.CommandContextImpl.initCommands(CommandContextImpl.java:581) at org.jboss.as.cli.impl.CommandContextImpl.<init>(CommandContextImpl.java:302) at org.jboss.as.cli.impl.CommandContextFactoryImpl.newCommandContext(CommandContextFactoryImpl.java:44) at org.jboss.as.cli.scriptsupport.CLI.connect(CLI.java:80) at cz.ladicek.foobar.Main.main(Main.java:8) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:144) Caused by: java.lang.ClassNotFoundException: org.jboss.logmanager.LogContextSelector at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 11 more
This is because CommandContextImpl's constructor calls EmbedServerHandler.create and for the EmbedServerHandler class to load, there has to be JBoss LogManager present on the classpath.
The wildfly-cli Maven module already has a dependency on JBoss LogManager, except that...
<dependency> <groupId>org.jboss.logmanager</groupId> <artifactId>jboss-logmanager</artifactId> <optional>true</optional> </dependency>
It's optional. I guess this made sense in WildFly Core 1.x which didn't have server embedding, but in WildFly Core 2.x, I wonder if the dependency should be mandatory.
Thoughts?
