Question

我要做的是为所有子项目推出几个父母poms。我有一个项目，包含一个父pom和两个子模块poms。如果这有所不同，那么所有三种包装都是pom型。当我部署时，它未能部署子模块，说它们被跳过。

这是我的一个孩子的poms，它们是唯一的变化是artifactId名称

儿童POM

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
        <modelVersion>4.0.0</modelVersion>

                <groupId>com.test.cpbx</groupId>
                <artifactId>parent</artifactId>
                <version>1.1-SNAPSHOT</version>

        <artifactId>rialto-parent</artifactId>
        <packaging>pom</packaging>
        <name>Rialto Parent POM</name>

</project>

输出

Answer 1

maven的输出有些混乱。

输出并不意味着它正在跳过构建模块或部署模块。

这是关于版本的重构的消息。输出告诉我们父pom拥有版本，子版本依赖于父pom。这意味着它不需要重构子模块pom.xml，因此它将反应器摘要中的子项打印为SKIPPED。

Answer 2

另一种可能性是，它意味着在能够构建这些模块之前该过程不起作用：

如果激活并行执行，它可以显示如下内容： [INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] [INFO] Parent Pom ........................................ SUCCESS [2.573s] [INFO] Child1 POM ........................................ SKIPPED [INFO] Child2 POM ........................................ SKIPPED [INFO] Dependent Sibling POM ............................. FAILURE [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------

如果依赖兄弟需要其中一个Childx工件，它可以在构建之前请求依赖。这会导致整个构建失败。

认为最后一次失败是因为其他人在构建期间错过了，这是误导性的。概述中的ABORTED状态可以节省一些时间。

为什么maven会释放我的子模块
