opendaylight - 如何使用 yang-version 1.1 模块的 ODL Yangtools maven 插件生成代码

问题描述

如何使用 OpenDaylight Yangtools maven 插件从 yang-version 1.1 模块生成 Java 代码？

我有一个 yang-version 1.1 模型（第一部分如下所示）

module o-ran-sc-my-desc-v1 {
    yang-version 1.1;
    namespace "urn:o-ran:my-desc:1.0";
    prefix rxad;

    organization
        "O-RAN Software Community";
    contact
        "www.o-ran.org";

我从 YANG 工具指南https://wiki.opendaylight.org/view/YANG_Tools:User_Guide开始构建 POM 文件并生成代码。那有旧版本和无效的代码生成器类名。我升级到插件版本 4.0.1，代码生成器版本 3.0.9，两者都是 Maven 中心的最新版本，并弄清楚了代码生成器类的名称。终于在 Maven 中得到了一些东西，但现在我得到了这个代码生成器错误：

[ERROR] Failed to execute goal org.opendaylight.yangtools:yang-maven-plugin:4.0.1:generate-sources (default) on project o1-netconf-client: 
Execution default of goal org.opendaylight.yangtools:yang-maven-plugin:4.0.1:generate-sources failed: An API incompatibility was 
encountered while executing org.opendaylight.yangtools:yang-maven-plugin:4.0.1:generate-sources: java.lang.NoSuchMethodError: 
org.opendaylight.yangtools.yang.model.util.SchemaNodeUtils.getAllTypeDefinitions(Lorg/opendaylight/yangtools/yang/model/api/DataNodeContainer;)Ljava/util/Collection;

为了完整起见，POM 的相关部分在下面发布。

                            <!-- if true, plugin will search for yang files also in dependent

我是否有可能使用不兼容的版本？

解决方案

找到了使用 Open Daylight 从 yang-version 1.1 模型生成 Java 绑定类的解决方案：

  1. 将父 pom 设置为 Open Daylight 文件。父级指定兼容版本，定义代码生成器等。
  2. 将 yang 文件放在目录 src/main/yang 中。该目录的存在从#1 激活所需的配置文件。

工作的 POM 出现在下面，它非常短，希望这可以为下一个人节省一些挫败感。

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.opendaylight.mdsal</groupId>
        <artifactId>binding-parent</artifactId>
        <version>5.0.9</version>
        <relativePath></relativePath>
    </parent>

    <packaging>jar</packaging>
    <name>Descriptive Name Goes Here</name>
    <version>0.0.1-SNAPSHOT</version>
</project>

当我运行“mvn install”时，执行的步骤包括生成源代码、测试、打包为 jar 等。这是关键的一个：
