在使用maven运行我的项目时获取camel-maven错误

Question

在使用以下命令运行我的项目时，我得到了以下错误: mvn -e camel:运行

错误未能在项目扯淡: nul : MojoExecutionException: org.apache.camel.spring.Main ->帮助1上执行目标MojoExecutionException(默认-cli)，org.apache.maven.lifecycle.LifecycleExecutionException:未能执行目标org.apache.camel:camel-maven-plugin:2.10。4:运行(默认-cli)项目放屁: null在org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:216) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:116) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:80) at org.apache.maven.lifecycle.internal.builder.singlethreaded.SingleThreadedBuilder.build(SingleThreadedBuilder.org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:120) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:347) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:154) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:582) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:214) at org.apache.maven.cli.MavenCli.main(MavenCli.java:158( sun.reflect.NativeMethodAccessorImpl.invoke0(Native方法)在sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)，sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)，java.lang.reflect.Method.invoke(Method.java:606)，org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:289)，org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:229)，org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(由: org.apache.maven.plugin.MojoExecutionException at org.apache.camel.maven.RunMojo.execute(RunMojo.java:482) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:132) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:208) . 19引起的: java.lang.ClassNotFoundException: org.apache.camel。java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) java.lang.ClassLoader.loadClass(ClassLoader.java:358) at org.apache.camel.maven.RunMojo$1.run(RunMojo.java:434) at java.lang.Thread.run(Thread.java:745)

下面是我的pom.xml文件中的依赖项：

<properties> 
<camel.version>2.10.4</camel.version> 
</properties> 
<dependency> 
<groupId>org.apache.camel</groupId> 
<artifactId>camel-core</artifactId> 
<version>${camel.version}</version> 
</dependency> 
<dependency> 
<groupId>org.apache.camel</groupId> 
<artifactId>camel-core-osgi</artifactId> 
<version>${camel.version}</version> 
</dependency> 
<dependency> 
<groupId>org.apache.camel</groupId> 
<artifactId>camel-spring</artifactId> 
<version>${camel.version}</version> 
<scope>compile</scope> 
</dependency> 
<dependency>

</dependency> 
<dependency>

<artifactId>camel-mina</artifactId> 
<version>${camel.version}</version> 
</dependency> 
<dependency> 
<groupId>org.apache.camel</groupId> 
<artifactId>camel-spring-integration</artifactId> 
<version>${camel.version}</version> 
</dependency> 
<dependency> 
<groupId>org.apache.camel</groupId> 
<artifactId>camel-test</artifactId> 
<version>${camel.version}</version> 
<scope>test</scope> 
</dependency> 
<dependency> 
<groupId>org.apache.camel</groupId> 
<artifactId>camel-test-spring</artifactId> 
<version>${camel.version}</version> 
<scope>test</scope> 
</dependency> 

移除作用域后出错。

我把显微镜移开了。我得到了这个错误:在运行main时发生了错误：

java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at org.apache.camel.maven。RunMojo$1.run(RunMojo.java:434) at java.lang.Thread.run(Thread.java:745)

Answer 1

这是一个类路径问题，这个类不是org.apache.camel.spring.Main，它来自camel-spring依赖项。因此，您应该删除编译范围(如只使用

<dependency> 
<groupId>org.apache.camel</groupId> 
<artifactId>camel-spring</artifactId> 
<version>${camel.version}</version> 
</dependency> 

Answer 2

我最近也犯了一个类似的错误。将目标SDK更改为OpenSDK可以使事情再次正常工作。
