title: Point to the sub folder Pom.xml from root pom.xml
body: <p>I am working on spring boot application(with rest calls included) and i want to host it on heroku. Application works perfectly in my local machine.
  Below is the Project Structure</p>
  
  <p>.git</p>
  
  <pre><code>foldera
  
  | 
    Mainclass
    Pom.xml
  
  folderb
  
  |
    other javacode
    pom.xml
  
  folderc
  
  |
    other javacode
    pom.xml
  
  Pom.xml(within root folder)
  </code></pre>
  
  <p>pom.xml of root folder is shown below</p>
  
  <pre><code>&lt;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"&gt;
      &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;
      &lt;parent&gt;
          &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
          &lt;artifactId&gt;spring-boot-starter-parent&lt;/artifactId&gt;
          &lt;version&gt;2.1.1.RELEASE&lt;/version&gt;
         &lt;/parent&gt;
          &lt;groupId&gt;root&lt;/groupId&gt;
      &lt;artifactId&gt;pomroot&lt;/artifactId&gt;
      &lt;version&gt;0.0.1-SNAPSHOT&lt;/version&gt;
      &lt;name&gt;Server Spring Boot&lt;/name&gt;
      &lt;description&gt;Spring boot server for svmapp&lt;/description&gt;
      &lt;properties&gt;
          &lt;java.version&gt;1.8&lt;/java.version&gt;
      &lt;/properties&gt;
      &lt;modules&gt;
          &lt;module&gt;./foldera&lt;/module&gt;
         &lt;/modules&gt;
  
  &lt;/project&gt;
  </code></pre>
  
  <p>I am using ./foldera to refer to subfolder using module tag. but this is not working.</p>
  
  <p>All the folders are maven folders and added to the classpath. Now what i need is that from parent folder i want to refer to the Pom.xml of folder a.</p>
  
  <p>How to achieve this?</p>
