[FIXED] Getting an camel-maven error while running my project using maven

Issue

I am getting the following error while running my project with this command: mvn -e camel:run

[ERROR] Failed to execute goal org.apache.camel:camel-maven-plugin:2.10.4:run (default-cli) on project bullshit: nul l: MojoExecutionException: org.apache.camel.spring.Main -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.camel:camel-maven-plugin:2.10. 4:run (default-cli) on project bullshit: null at 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. java:51) at 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) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:289) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:229) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:415) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:356) Caused by: 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 more Caused by: java.lang.ClassNotFoundException: org.apache.camel.spring.Main at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at 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)

Here's what I have for dependency in my pom.xml file:

<properties> 
<camel.version>2.10.4</camel.version> 
</properties> 
<dependency> 
<groupId>org.apache.camel</groupId> 
<artifactId>camel-core</artifactId>

</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-mina</artifactId>

</dependency> 
<dependency>

<artifactId>camel-spring-integration</artifactId> 
<version>${camel.version}</version> 
</dependency> 
<dependency>

<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> 

Error after removing scope.

I removed the scope. I am getting this error:Error occurred while running main from:

org.apache.camel.spring.Main java.lang.ClassNotFoundException: org.apache.camel.spring.Main at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at 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)

Solution

Its a classpath issue, this class is not found org.apache.camel.spring.Main, which is from the camel-spring dependency. So you should remove the compile scope, eg just use

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