maven parent pom dependencies继承版本但不继承排除项

Question

我有父pom,其中包含所有项目版本和排除项我希望从子项中的父项具有相同的排除项,我该如何实现它.

son-project项目继承了他的父亲版本,但是拿了神器a,我希望他避免采取我怎么做？

我的目标是让字母jar没有依赖

<project>
  <modelVersion>4.0.0</modelVersion>
  <artifactId>parent-pom</artifactId>
  <groupId>parent</groupId>
  <version>1.0.0</version>
  <packaging>pom</packaging>
  <dependencies>
    <dependency>
        <groupId>com.somthing.ltetters</groupId>
        <artifactId>ltetters</artifactId>
        <version>1.4</version>
        <exclusions>
            <exclusion>
                <groupId>com.somthing.ltetters</groupId>
                <artifactId>a</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
  </dependencies>

<?xml version="1.0" encoding="UTF-8"?>

  <parent>

  </parent>
  <dependencies>
    <dependency>
        <groupId>com.somthing.ltetters</groupId>
        <artifactId>ltetters</artifactId>
    </dependency>
  </dependencies>

Answer 1

如果已在父pom中指定了依赖项,则它将由所有子工件继承,并且您不需要再次指定它.如果您实际上不希望在默认情况下继承它,那么请使用父pom中的< dependencyManagement >,然后在没有version或exclude的子项目中指定依赖项.所以,你的父pom将如下所示:

<project>
  <modelVersion>4.0.0</modelVersion>
  <artifactId>parent-pom</artifactId>
  <groupId>parent</groupId>
  <version>1.0.0</version>
  <packaging>pom</packaging>
  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>com.somthing.ltetters</groupId>
        <artifactId>ltetters</artifactId>
        <version>1.4</version>
        <exclusions>
            <exclusion>
                <groupId>com.somthing.ltetters</groupId>
                <artifactId>a</artifactId>
            </exclusion>
        </exclusions>
      </dependency>
    </dependencies>
    ...
  <dependencyManagement>
  ...

所有子项目仍然看起来与您的问题相同.
