Question

我正在尝试从Maven本书中获取此示例Maven多模块项目以进行构建和安装，但它说从属兄弟姐妹不可用。

我首先尝试编译并安装天气模型，它运行正常。

[INFO] Installing /Users/johne/IdeaProjects/WeatherApp/weather-web/weather-model/target/weather-model-1.0-SNAPSHOT.jar to /Users/johne/.m2/repository/com/testcom/weather-model/1.0-SNAPSHOT/weather-model-1.0-SNAPSHOT.jar

但是，当我从weather-web目录尝试mvn install时，它会失败。

包含依赖项中的问题。我接受了您的github代码并更改了持久性pom。

   <dependency>
        <groupId>com.siriuscom</groupId>
        <artifactId>weather-model</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

siruscom更改为siriuscom，它的工作原理就像一个魅力，在您发布不同组ID的问题中，它也有效。

始终复制粘贴，从不手动键入。
