title: Errors occur when include many 3rd party jars to one simple spring boot project
body: <p>Whether it's possible to use API from one JAR from myself, while not include its dependency?</p>
  
  <p>I created one standalone maven project(A) which is an API module and it uses many 3rd party jars and should be used in several projects. But in one spring boot project(B), since A introduced its dependencies, the spring boot project cannot work well.</p>
  
  <p>If A is excluded from pom, then spring boot works well. But I do need several APIs from it. How should I solve this problem?</p>
  
  <p>At first, everything works well. It is a pure console application.
  Pom is something like below.</p>
  
  <pre><code>&lt;dependencies&gt;
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
          &lt;artifactId&gt;spring-boot-starter&lt;/artifactId&gt;
      &lt;/dependency&gt;
      &lt;!-- 
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
          &lt;artifactId&gt;spring-boot-starter-web&lt;/artifactId&gt;
      &lt;/dependency&gt;
       --&gt;
      &lt;!-- 
      &lt;dependency&gt;
          &lt;groupId&gt;InsuranceWrapper&lt;/groupId&gt;
          &lt;artifactId&gt;InsuranceWrapper&lt;/artifactId&gt;
          &lt;version&gt;1.0&lt;/version&gt;
      &lt;/dependency&gt;
       --&gt; 
      &lt;/dependencies&gt;
  </code></pre>
  
  <p>Then I add InsuranceWrapper to it, it will has one error.</p>
  
  <pre><code>java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration$TransactionManagementConfiguration due to org/springframework/web/servlet/view/freemarker/FreeMarkerConfigurer not found. Make sure your own configuration does not rely on that class. This can also happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)

  </code></pre>
  
  <p>Then I thought spring boot may think I am a web project. So I add spring boot web. Now another error occurs.</p>
  
  <pre><code>org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;

  </code></pre>
  
  <p>Searched these errors, no clues at all. My A project is a complex spring+hibernate project. That's why I ask this question and just want a clean environment for B while use several APIs from A.</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>add spring-boot-starter-freemarker to fix first error</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>Update mvn tree</p>

  <p>But since spring web is included.. It will start one tomcat from behind, which is very annoying..</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>Since any spring-web will make spring boot think now it is a web project, at last all spring web is removed. And also  spring-boot-starter-freemarker is removed either, since it is not used actually.</p>
