Question

我有一个现有的maven项目，我计划使用WebLogic Server进行部署。由于我需要一个ear文件，因此我按照以下步骤创建jar module和war module，我后来计划将其包含在parent module中。但是，当我创建jar模块时，文件夹在eclipse中反映的那一刻，我收到有关pom.xml的错误消息。该错误表示Project build error: Non-readable POM pom.xml /*ProjectName*JARModule line 1 Maven pom Loading Problem。知道为什么会这样吗？当我尝试创建war模块时也会发生同样的情况。直到我没有准备好这两个模块，我才能继续制作ear模块并包括两者。非常感谢！ **更新 - **这是我的parent project pom.xml（我正确地登上了它并选择创建一个名为projectnameJAR和projectnameWAR甚至projectnameEAR的新模块 -

以下是为pom模块生成的JAR -

    <?xml version="1.0"?>

为pom模块生成WAR -

Answer 1

我有一个可以使用eclipse和weblogic-10.3.6的多模块项目。你能否证实你有相同的树形结构？

parent-module
|_module-war
|   |_pom.xml
|_module-jar
|  |_pom.xml
|_module-ear
|  |_pom.xml
|_pom.xml

parent-module / module-ear / pom.xml看起来像这样。

<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>group-module-ear</groupId>
  <artifactId>module-ear</artifactId>
  <version>0.0.2</version>
  <packaging>ear</packaging>   
  <parent>
       <groupId>group.parent</groupId>
       <artifactId>parent</artifactId>
       <version>0.0.1</version>  
  </parent>
  <dependencies>
    <dependency>
        <groupId>group-module-war</groupId>
        <artifactId>module-war</artifactId>
        <version>0.0.2</version>
        <type>war</type>
    </dependency>
     <dependency>
        <groupId>group-module-jar</groupId>
        <artifactId>module-jar</artifactId>
        <version>0.0.2</version>
    </dependency>   
  </dependencies>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-ear-plugin</artifactId>
        <version>2.10</version>
        <configuration>

        <defaultLibBundleDir>APP-INF/lib</defaultLibBundleDir>           
           <modules> 
             <webModule>
               <groupId>group-module-war</groupId>
               <artifactId>module-war</artifactId>
               <bundleDir>/</bundleDir>
             </webModule>
             <jarModule>
               <groupId>group-module-jar</groupId>
               <artifactId>module-jar</artifactId>
               <bundleDir>/</bundleDir>
             </jarModule>             
          </modules>          
        </configuration>
      </plugin>

  </build>

</project>

parent-module / pom.xml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>
  <groupId>ETIC_J</groupId>
  <artifactId>ETIC_J</artifactId>
  <version>0.0.1</version>
  <packaging>pom</packaging>  

   <properties>
           <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
           <artifactory.url>localhost:8080</artifactory.url>
   </properties>

    <modules>      
         <module>module-jar</module>   
         <module>module-war</module>         
         <module>metier-etic-ear</module>               
    </modules> 

</project>

Answer 2

你的pom似乎没问题，所以这可能是你父母和他孩子之间的路径问题。

parent-module (i.e. your eclipse workspace)
|_Project_nameJARModule
|   |_pom.xml
|_Project_nameWARModule
|  |_pom.xml
|_Project_nameEARodule
|  |_pom.xml
|_pom.xml

这与已发布的@Aurelien树相同。如果不像这样构造树，则必须定义父路径和模块路径。

工作原理：

<modules>
    <module>../path/to/your/child/module/</module>
</modules>

<parent>
    <groupId>com.mycompany.app</groupId>
    <artifactId>my-app</artifactId>
    <version>1</version>

    <!-- define the path to the parent -->
    <relativePath>../path/pom.xml</relativePath> 
</parent>

如果您没有定义特定的<relativePath>

，则上面的树结构是默认的

所以在经过大量的敲击之后，我决定将工作区切换一次并检查。和ta-daa。就是这样。问题解决了。由于某种原因，Eclipse在我当时的工作空间中行为不端。我创建了一个较新的工作区并尝试了同样的事情，一切顺利。希望这可以帮助。 :)

Eclipse无法找到pom.xml位置
