在创建自定义异常时,如果我们想要创建一个已检查的 Exception,我们会扩展Exception类,对于未经检查的异常,我们会扩展RuntimeException类.我的问题是,当JVM全部是Exception类的子类时,JVM如何处理RuntimeException和Exception的子类.

我有一个项目层次结构:

A - pom.xml
|__ B - pom.xml
    |__ C - pom.xml

该属性project.version在A中定义的pom.xml中定义.其他两个pom指定父标记和相应父pom的相应相对路径.

<parent>
        <groupId>com.GRP.id</groupId>
        <artifactId>ARTIFACT_ID</artifactId>
        <version>${project.version}</version>
        <relativePath>../pom.xml</relativePath>
</parent>

这里的问题是maven无法解析$ {project.version}并按原样使用它.从A/B/C执行时抛出以下异常:

[ERROR] The build could not read 1 project -> [Help 1]
org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:
