编译自定义 OpenDaylight API 时出错

Question

我正在尝试根据https://wiki.opendaylight.org/view/OpenDaylight_Controller:MD-SAL:Startup_Project_Archetype上的 API 教程创建自定义 API

工具：OpenDaylight Lithium、Eclipse、Maven 3.3.9

我可以编译该文件夹api，但不能编译impl( FlowImpl.java) 中的文件夹。

这是错误消息：

[INFO] Starting audit...
/home/shaoxu/Desktop/distribution-karaf-0.3.3-Lithium-SR3/flow/impl/src/main/java/org/opendaylight/flow/impl/FlowImpl.java:1: Line does not match expected header line of '^/[*]+$'.
Audit done.
[INFO] There is 1 error reported by Checkstyle 6.2 with check-license.xml ruleset.
[ERROR] src/main/java/org/opendaylight/flow/impl/FlowImpl.java[1] (header) RegexpHeader: Line does not match expected header line of '^/[*]+$'.

Eclipse 中没有错误信息。

这是源代码：

package org.opendaylight.flow.impl;

import java.util.concurrent.Future;

import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.flow.rev150105.FlowService;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.flow.rev150105.FlowPathInput;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.flow.rev150105.FlowPathOutput;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.flow.rev150105.FlowPathOutputBuilder;
import org.opendaylight.yangtools.yang.common.RpcResult;
import org.opendaylight.yangtools.yang.common.RpcResultBuilder;

public  class FlowImpl implements FlowService {

      @Override
        public Future<RpcResult<FlowPathOutput>> flowPath(FlowPathInput input) {
          FlowPathOutputBuilder flowBuilder = new FlowPathOutputBuilder();
          flowBuilder.setPath(input.getNodes());
            return RpcResultBuilder.success(flowBuilder.build()).buildFuture();
        }

}

错误是什么？

您收到的错误是由 OpenDaylight 中每个文件开头的版权/许可证标头的强制格式引起的：

\n\n

如果您使用原型，则应该已为您生成此标头。有两种方法可以解决该问题：要么添加上面的许可证头（如果您对许可证感到满意），要么禁用许可证检查 \xe2\x80\x94 如果您想执行后者，请编辑您的问题并添加您正在使用的 POM，impl以便我可以解释如何进行操作。

您提到您正在使用锂，我强烈建议改用铍甚至硼进行新开发。目前，Beryllium 的 wiki 页面大多是最新的。
