Question

我正在使用速度为log4j追加程序编写自定义布局，但无法使其运行

以下错误：

java.lang.NoClassDefFoundError： org / apache / commons / collections / ExtendedProperties位于 org.apache.velocity.runtime.RuntimeInstance。（RuntimeInstance.java:183）在 org.apache.velocity.app.VelocityEngine。（VelocityEngine.java:60）在 nz.ac.massey.cs.sdc.assign1.s06013597.VelocityLayout。（VelocityLayout.java:16）在 nz.ac.massey.cs.sdc.assign1.s06013597.VelocityLayoutTest.test（VelocityLayoutTest.java:36）在 java.base / jdk.internal.reflect.NativeMethodAccessorImpl.invoke0（本机方法） java.base / jdk.internal.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:62）在 java.base / jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43）在java.base / java.lang.reflect.Method.invoke（Method.java:564）在 org.junit.runners.model.FrameworkMethod $ 1.runReflectiveCall（FrameworkMethod.java:50）在 org.junit.internal.runners.model.ReflectiveCallable.run（ReflectiveCallable.java:12）在 org.junit.runners.model.FrameworkMethod.invokeExplosively（FrameworkMethod.java:47）在 org.junit.internal.runners.statements.InvokeMethod.evaluate（InvokeMethod.java:17）在org.junit.runners.ParentRunner.runLeaf（ParentRunner.java:325）处 org.junit.runners.BlockJUnit4ClassRunner.runChild（BlockJUnit4ClassRunner.java:78）在 org.junit.runners.BlockJUnit4ClassRunner.runChild（BlockJUnit4ClassRunner.java:57）在org.junit.runners.ParentRunner处$ 3.run（ParentRunner.java:290）在 org.junit.runners.ParentRunner $ 1.schedule（ParentRunner.java:71）在 org.junit.runners.ParentRunner.runChildren（ParentRunner.java:288）在 org.junit.runners.ParentRunner.access $ 000（ParentRunner.java:58）在 org.junit.runners.ParentRunner $ 2.evaluate（ParentRunner.java:268）在 org.junit.runners.ParentRunner.run（ParentRunner.java:363）在 org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run（JUnit4TestReference.java:86）在 org.eclipse.jdt.internal.junit.runner.TestExecution.run（TestExecution.java:38）在 org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests（RemoteTestRunner.java:538）在 org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests（RemoteTestRunner.java:760）在 org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run（RemoteTestRunner.java:460）在 org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main（RemoteTestRunner.java:206）造成原因：java.lang.ClassNotFoundException： org.apache.commons.collections.ExtendedProperties位于 java.base / jdk.internal.loader.BuiltinClassLoader.loadClass（BuiltinClassLoader.java:582）在 java.base / jdk.internal.loader.ClassLoaders $ AppClassLoader.loadClass（ClassLoaders.java:190）在java.base / java.lang.ClassLoader.loadClass（ClassLoader.java:499） ...另外27个

Answer 1
