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(接下来显示的第一部分)
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开始构造一个POM文件并生成代码。它具有旧版本tho和无效的代码生成器类名称。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 Central的最新版本,并弄清楚了代码生成器类的名称。终于在maven中工作了一些,但是现在我收到了此代码生成器错误:
[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,下面发布了POM的相关部分。
<plugin>
<groupId>org.opendaylight.yangtools</groupId>
<artifactId>yang-maven-plugin</artifactId>
<version>4.0.1</version>
<executions>
<execution>
<goals>
<goal>generate-sources</goal>
</goals>
<configuration>

</codeGeneratorClass>
<!-- directory into which generated files will be placed -->

</outputBaseDir>
</generator>
</codeGenerators>
<!-- if true, plugin will search for yang files also in dependent
projects -->
<inspectDependencies>true</inspectDependencies>
</configuration>
</execution>
</executions>

<dependency>

<artifactId>maven-sal-api-gen-plugin</artifactId>
<version>3.0.9</version>
<type>jar</type>
</dependency>
</dependencies>
</plugin>
是否可能使用的版本不兼容?
[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:
正在工作的POM出现在下面,很短,希望这可以节省下一个人的挫败感。

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:
