Wildfly 10 Java EE EAR项目中缺少工件错误

Question

我使用向导创建了一个Java EE EAR项目。我在ear和web子项目的pom文件中都有一个错误。ejb pom文件没有错误。

这就是我得到的错误...

缺少工件org.jboss.ejb3:jboss-ejb3-web:war:1.0.0

下面是ear子项目的pom文件

错误发生在pom文件的这个区域。

  <dependency>
     <groupId>org.jboss.ejb3</groupId>
     <artifactId>jboss-ejb3-ejb</artifactId>
     <type>ejb</type>
     <scope>provided</scope>
  </dependency>

如何解决此错误？

Answer 1

您的父pom文件中必须有模块部分，并确保依赖项按顺序排列在依赖项下。

    <modules>
        <module>core-module</module>
        <module>depends-on-core</module>
        <module>depends-on-core2</module>
        <module>depends-on-depends-on-core</module>
    </modules>

在安排更新maven之后。
