我正在尝试加载一个外部 bmpn2 文件并在 Apache Karaf 环境中运行它。这是bmpn2文件

这是用于启动工作流的代码
File file = new File(workflowFile);
if(file == null || !file.exists()) {
throw new FileNotFoundException("Specified file path is invalid.");
}
RuntimeEnvironment environment = RuntimeEnvironmentBuilder.getEmpty()
.addAsset(ResourceFactory.newFileResource(file ), ResourceType.BPMN2)
.get();
RuntimeManager manager = RuntimeManagerFactory.Factory.get().newSingletonRuntimeManager(environment);
RuntimeEngine runtime = manager.getRuntimeEngine(EmptyContext.get());
KieSession ksession = runtime.getKieSession();
ksession.startProcess(processId);
System.out.println("Proc started!");
其中，workflowFile表示保存在某个目录中的 bpmn2 文件的绝对 URL。当我在 Karaf（作为捆绑激活器或 Karaf 命令扩展）上运行此代码时，我收到以下错误
java.lang.IllegalArgumentException: Cannot add asset: Error importing : 'com.test.ToolsServicesOne',Error importing : 'com.test.ToolsServicesTwo',
at org.jbpm.runtime.manager.impl.SimpleRuntimeEnvironment.addAsset(SimpleRuntimeEnvironment.java:111)
at org.jbpm.runtime.manager.impl.RuntimeEnvironmentBuilder.addAsset(RuntimeEnvironmentBuilder.java:341)
注意 如果我运行与简单 JUnit 测试相同的类，我不会收到任何错误
谁能帮我解决这个问题？我尝试搜索 google/JBPM 论坛，但找不到任何解决方案。感谢您在此线程上的时间！
