无法调用avro-maven插件

Question

我的问题类似于无法使用Maven从.avsc编译和创建.avro文件

我已经尝试了所有可能的东西,检查maven项目100次,仍然我无法运行avro-maven插件来生成我的avsc文件的代码.

我已阅读以下帖子并遵循相同的规定,但没有成功 http://grepalex.com/2013/05/24/avro-maven/ https://github.com/phunt/avro-maven-plugin

我下载了上面的maven项目,这里结果也一样.

但没有生成代码.

我强烈认为Maven是我的致命敌人,我永远无法用apache项目做任何工作只是因为我无法让maven工作.也许我应该考虑回到更健全的C/C++世界,它不需要互联网连接来编译我的源代码.

下面是我已成功使用的示例 POM 文件。我的猜测是您的 sourceDirectory 和 outputDirectory 标记未正确定义......
