title: Maven transient dependency (library/jar vaadin json) is not being excluded
body: <p>I have the problem that maven is including 2 versions of the <code>org.json</code> package from two different dependencies.</p>
  
  <p>I have the following:</p>
  
  <pre><code>&lt;dependency&gt;
              &lt;groupId&gt;com.google.code.gson&lt;/groupId&gt;
              &lt;artifactId&gt;gson&lt;/artifactId&gt;
          &lt;/dependency&gt;
  </code></pre>
  
  <p>But I also have the following outputs ( <strong>vaadin is the one I don't want</strong> ):</p>
  
  <pre><code>[INFO] +- org.springframework.boot:spring-boot-starter-test:jar:2.0.3.RELEASE:test
  </code></pre>
  
  <p>The dependency tree is showing the following two entries:</p>

  <pre><code>[INFO] +- org.json:json:jar:20171018:compile
  </code></pre>
  
  <p>I have tried the following but the annoying vaadin jar is still being included in the project:</p>
  
  <pre><code>&lt;dependency&gt;
              &lt;groupId&gt;com.google.code.gson&lt;/groupId&gt;
              &lt;artifactId&gt;gson&lt;/artifactId&gt;
          &lt;/dependency&gt;
  
          &lt;dependency&gt;
              &lt;groupId&gt;org.mbak.test&lt;/groupId&gt;
              &lt;artifactId&gt;mb-cloud-starter-test&lt;/artifactId&gt;
              &lt;scope&gt;test&lt;/scope&gt;
              &lt;exclusions&gt;
                  &lt;exclusion&gt;
                      &lt;groupId&gt;com.vaadin.external.google&lt;/groupId&gt;
                      &lt;artifactId&gt;android-json&lt;/artifactId&gt;
                  &lt;/exclusion&gt;
              &lt;/exclusions&gt;
          &lt;/dependency&gt;
  </code></pre>
  
  <p>This is causing a method not found exception. 
  If we go and delete the JAR from the packaged war manually, everthing is fine!</p>

  <p>And because of vaadin I was getting:</p>
  
  <pre><code>org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: org.json.JSONObject.entrySet()Ljava/util/Set;

  <h2>Update</h2>
  
  <p>I tried the following but it still doesn't fail to exclude vaadin:</p>
  
  <pre><code>&lt;dependency&gt;
              &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
              &lt;artifactId&gt;spring-boot-starter-test&lt;/artifactId&gt;
              &lt;scope&gt;test&lt;/scope&gt;
              &lt;exclusions&gt;
                  &lt;exclusion&gt;
                      &lt;groupId&gt;com.vaadin.external.google&lt;/groupId&gt;
                      &lt;artifactId&gt;android-json&lt;/artifactId&gt;
                  &lt;/exclusion&gt;
              &lt;/exclusions&gt;
          &lt;/dependency&gt;
  </code></pre>
  
  <p>Additionally, I am noticing the behavior is different when you do <code>mvn spring-boot:run</code> and when you run a packaged war file.</p>
  
  <p>When running the packaged war file we have the error. When we do spring-boot:run we do not. </p>
  
  <h2>Weird fix</h2>
  
  <p>A colleague of mine fixed this by entering the following exclusion ( but I don't understand why it worked ):</p>
  
  <pre><code>&lt;dependency&gt;
              &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
              &lt;artifactId&gt;spring-boot-configuration-processor&lt;/artifactId&gt;
              &lt;optional&gt;true&lt;/optional&gt;
              &lt;exclusions&gt;
                  &lt;exclusion&gt;
                      &lt;groupId&gt;com.vaadin.external.google&lt;/groupId&gt;
                      &lt;artifactId&gt;android-json&lt;/artifactId&gt;
                  &lt;/exclusion&gt;
              &lt;/exclusions&gt;
          &lt;/dependency&gt;
  </code></pre>
  
  <p><strong>Anyone got any ideas?</strong></p>
