```gradle dependencies { lib (group: 'org.codehaus.groovy', name: 'groovy-all', version: '2.4.11') } ``` - `gradle dependencies` command shows the above jar… but - `gradle build` fails showing **RuntimeException** as shown below, ```gradle java.lang.RuntimeException: Could not resolve class named groovy.util.logging.Log4j2 at org.codehaus.groovy.transform.LogASTTransformation.createLoggingStrategy(LogASTTransformation.java:162) ``` ---

During gradle compilation process, this exception comes. It comes only for `groovy.util.logging.Log4j2` and not for other classes of groovy. And this behavior is totally random if we add `groovy-all` dependency in some place of `dependencies` block, this exception does not come. Unable to identify a reproducible behavior for this. Any help will be highly helpful ```gradle General error during semantic analysis: Could not resolve class named groovy.util.logging.Log4j2 java.lang.RuntimeException: Could not resolve class named groovy.util.logging.Log4j2 at org.codehaus.groovy.transform.LogASTTransformation.createLoggingStrategy(LogASTTransformation.java:162) at org.codehaus.groovy.transform.LogASTTransformation.visit(LogASTTransformation.java:54) at org.codehaus.groovy.transform.ASTTransformationVisitor.visitClass(ASTTransformationVisitor.java:129) at org.codehaus.groovy.transform.ASTTransformationVisitor$2.call(ASTTransformationVisitor.java:172) at org.codehaus.groovy.control.CompilationUnit.applyToPrimaryClassNodes(CompilationUnit.java:970) at org.codehaus.groovy.control.CompilationUnit.doPhaseOperation(CompilationUnit.java:548) at org.codehaus.groovy.control.CompilationUnit.processPhaseOperations(CompilationUnit.java:526) at org.codehaus.groovy.control.CompilationUnit.compile(CompilationUnit.java:503) at org.codehaus.groovy.control.CompilationUnit.compile(CompilationUnit.java:482) at org.gradle.api.internal.tasks.compile.ApiGroovyCompiler.execute(ApiGroovyCompiler.java:275) at org.gradle.api.internal.tasks.compile.ApiGroovyCompiler.execute(ApiGroovyCompiler.java:68) at org.gradle.api.internal.tasks.compile.GroovyCompilerFactory$DaemonSideCompiler.execute(GroovyCompilerFactory.java:87) at org.gradle.api.internal.tasks.compile.GroovyCompilerFactory$DaemonSideCompiler.execute(GroovyCompilerFactory.java:75) at org.gradle.api.internal.tasks.compile.daemon.AbstractDaemonCompiler$CompilerWorkAction.execute(AbstractDaemonCompiler.java:128) at org.gradle.workers.internal.DefaultWorkerServer.execute(DefaultWorkerServer.java:50) at org.gradle.workers.internal.AbstractClassLoaderWorker$1.create(AbstractClassLoaderWorker.java:47) at org.gradle.workers.internal.AbstractClassLoaderWorker$1.create(AbstractClassLoaderWorker.java:37) at org.gradle.internal.classloader.ClassLoaderUtils.executeInClassloader(ClassLoaderUtils.java:98) at org.gradle.workers.internal.AbstractClassLoaderWorker.executeInClassLoader(AbstractClassLoaderWorker.java:37) at org.gradle.workers.internal.IsolatedClassloaderWorker.execute(IsolatedClassloaderWorker.java:49) at org.gradle.workers.internal.WorkerDaemonServer.execute(WorkerDaemonServer.java:84) 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 org.gradle.process.internal.worker.request.WorkerAction$1.call(WorkerAction.java:129) at org.gradle.process.internal.worker.child.WorkerLogEventListener.withWorkerLoggingProtocol(WorkerLogEventListener.java:41) at org.gradle.process.internal.worker.request.WorkerAction.run(WorkerAction.java:126) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.gradle.internal.dispatch.ReflectionDispatch.dispatch(ReflectionDispatch.java:36) at org.gradle.internal.dispatch.ReflectionDispatch.dispatch(ReflectionDispatch.java:24) at org.gradle.internal.remote.internal.hub.MessageHubBackedObjectConnection$DispatchWrapper.dispatch(MessageHubBackedObjectConnection.java:182) at org.gradle.internal.remote.internal.hub.MessageHubBackedObjectConnection$DispatchWrapper.dispatch(MessageHubBackedObjectConnection.java:164) at org.gradle.internal.remote.internal.hub.MessageHub$Handler.run(MessageHub.java:412) at org.gradle.internal.concurrent.ExecutorPolicy$CatchAndRecordFailures.onExecute(ExecutorPolicy.java:64) at org.gradle.internal.concurrent.ManagedExecutorImpl$1.run(ManagedExecutorImpl.java:48) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at org.gradle.internal.concurrent.ThreadFactoryImpl$ManagedThreadRunnable.run(ThreadFactoryImpl.java:56) at java.lang.Thread.run(Thread.java:748) 10 errors ```
