Question

我在docs.wso2.com上尝试了这个tutorial，但是步骤从原型创建Maven项目模板

mvn archetype:generate -DarchetypeGroupId=org.wso2.carbon.extension.archetype -DarchetypeArtifactId=org.wso2.carbon.extension.esb.connector-archetype -DarchetypeVersion=2.0.0 -DgroupId=org.wso2.carbon.connector -DartifactId=org.wso2.carbon.connector.helloworld -Dversion=1.0.0 -DarchetypeRepository=http://maven.wso2.org/nexus/content/repositories/wso2-public/

失败并显示错误：

...

    [WARNING] Use -DarchetypeRepository=<your repository> if archetype's repository is elsewhere.

文档不好或我的错误？
有一个原型开始编写自定义Java连接器吗？

Answer 1

在错误消息中，它显示为＆＃34; http://repo.maven.apache.org/maven2＆＃34;。你可以检查maven版本，如果它不是maven2，安装maven2然后尝试该原型。

Answer 2

检查您当地的maven仓库中是否有：

[MAVEN_REPO]\org\wso2\carbon\extension\archetype\org.wso2.carbon.extension.esb.connector-archetype\2.0.0\org.wso2.carbon.extension.esb.connector-archetype-2.0.0.jar

[MAVEN_REPO]\org\wso2\carbon\extension\archetype\org.wso2.carbon.extension.esb.connector-archetype\2.0.0\org.wso2.carbon.extension.esb.connector-archetype-2.0.0.pom

最后再次使用-e并删除

中的所有内容

[MAVEN_REPO]\org\wso2\carbon\extension\archetype\org.wso2.carbon.extension.esb.connector-archetype\2.0.0\

Answer 3

转到https://github.com/wso2-extensions/archetypes并克隆您有兴趣构建的原型项目。

如果mvn create命令失败，请使用pom创建一个java项目在原型项目中可用。

对pom中不同工件的版本进行更正在wso2 maven存储库中可用。

编写WSO2连接器：从原型创建Maven项目模板不起作用
