我正在尝试设置一个多模块Maven项目,并且模块间依赖关系显然没有正确设置.

我有:

<modules>
  <module>commons</module>
  <module>storage</module>
</modules>

在父POM(具有包装类型的pom)和子目录中commons/,storage/它们定义具有相同名称的JAR poms.

存储取决于Commons.

在主(主)目录中,我运行mvn dependency:tree并看到:

[INFO] Building system

我有一个项目有依赖A.项目正在打包到WAR和依赖A - 进入jar.另一个依赖关系B,也依赖于A.我想打包项目,当项目B打包时,它必须重建其依赖关系A而不是获得编译的依赖关系.请帮忙,我怎样才能做到这一点

我有一个非常复杂的项目(大约100个模块),我想在其上运行mvn dependency:tree.它失败了,抱怨无法解决的依赖关系.否则该项目编制正常.所以我创建了我可以提出的最基本的项目,它仍然失败并出现同样的错误.显然要么我必须做一些非常基本的错误,或者maven-dependency-plugin还没有被任何人使用过.以下是测试项目的三个POM:

pom.xml中:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<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.example</groupId>
    <artifactId>root</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>
    <modules>
        <module>foo</module>
        <module>bar</module>
    </modules>
</project>

富/ pom.xml中:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<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.example</groupId>
    <artifactId>foo</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>jar</packaging>
</project>

酒吧/ pom.xml中:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<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.example</groupId>
    <artifactId>bar</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>jar</packaging>
    <dependencies>
        <dependency>
            <groupId>com.example</groupId>
            <artifactId>foo</artifactId>
            <version>1.0.0-SNAPSHOT</version>
        </dependency>
    </dependencies>
</project>

然后我mvn dependency:tree在顶级目录中发出以下命令并获得以下输出:
