无法在 pom.xml中将包装作为战争添加到日食中的专家项目中

Question

我是新手。我一直在用pom.xml在日食中做一个专家项目，如下所示： <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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.walmart.move.nim.damage</groupId> <artifactId>damages-external-services-parent</artifactId> <version>1.0.36-SNAPSHOT</version> <packaging>war</packaging> #### THIS LINE IS GIVING ERROR</parent><artifactId>damages-external-services</artifactId><name>damages-external-services</name><description>Damages external services.

Answer 1

包装标签应在标签之外。<packaging></parent>

</parent>
<packaging>war</packaging>

Answer 2

母POM可以用包装pom声明。它并不意味着是分布式的，因为它只从其他项目中引用。

Maven 父 pom 可以包含几乎所有内容，这些内容可以继承到子 pom 文件中，例如

母体聚甲醛

<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/xsd/maven-4.0.0.xsd;

    <modelVersion>4.0.0</modelVersion>

 

    <groupId>com.demo</groupId>

    <artifactId>Examples</artifactId>

    <version>0.0.1-SNAPSHOT</version>

    <packaging>pom</packaging>

 

    <name>Parent POM</name>

    <url>http://maven.apache.org</url>

 

    <properties>

....

儿童聚甲醛

<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">

 

    <!--The identifier of the parent POM-->

    <parent>

        <groupId>com.demo</groupId>

        <artifactId>Examples</artifactId>

        <version>0.0.1-SNAPSHOT</version>

    </parent>

 

    <modelVersion>4.0.0</modelVersion>

    <artifactId>Examples</artifactId>

    <name>Child POM</name>

    <packaging>jar</packaging>

 

    <dependencies>
