由于依赖关系而无法编译Maven项目。

Question

Why do I get an error when I try to clean and compile my Maven project from the root folder? I use the top level POM for defining dependencies in the dependencyManagement element. I want to use it in the library projects.

I have the following Maven project structure:

POM
    Library1
    POM
        Module1
        POM
        Module2
        POM
    Library2
        Module1
        POM
        Module2
        POM

From top level POM:

 <dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.jboss.spec</groupId>
            <artifactId>jboss-javaee-6.0</artifactId>
            <version>1.0.0.Final</version>
            <type>pom</type>
            <scope>provided</scope>
        </dependency>
  </dependencyManagement>

Library POM:

<dependencies>
    <dependency>
        <groupId>org.jboss.spec</groupId>
        <artifactId>jboss-javaee-6.0</artifactId>
    </dependency>
</dependencies>

Answer 1

I needed to add type element in the dependency.

<dependencies>
    <dependency>
        <groupId>org.jboss.spec</groupId>
        <artifactId>jboss-javaee-6.0</artifactId>
        <type>pom</type>
    </dependency>
</dependencies>
