hibernate-maven-plugin 버전 2.2에서 버전 3.0으로 전환 할 때 NullPointerException이 발생했습니다.

Question

pom.xml 종속성의 버전을 업데이트 중이며 hibernate3-maven-plugin의 버전을 변경할 때 막연한 오류가 발생했습니다.

<plugin> 
    <!-- Run "mvn hibernate3:hbm2ddl" to generate schema --> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>hibernate3-maven-plugin</artifactId> 
    <version>2.2</version> 
</plugin> 

, 모든 것이 성공적으로 컴파일 버전 2.2

<plugin> 
    <!-- Run "mvn hibernate3:hbm2ddl" to generate schema --> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>hibernate3-maven-plugin</artifactId> 
    <version>3.0</version> 
</plugin>

및

mvn hibernate3:hbm2ddl 

은 주석이 달린 클래스에서 올바른 스키마를 만듭니다. 다음과 같이

[ERROR] Failed to execute goal org.codehaus.mojo:hibernate3-maven-plugin:3.0:hbm2ddl (default-cli) on project myProject: There was an error creating the AntRun task. NullPointerException -> [Help 1] 

전체 스택 추적은 다음과 같습니다 : 나는 다시 hbm2ddl을 명령을 실행할 때 아무 것도 있지만, 다음과 같은 오류의 버전 결과를 변경하지

나는 다시 들으면 버전 2.2에서는 모든 것이 잘 작동합니다. 그리고 단순히 최신 종속성을 갖는 것 이외의 어떤 특별한 이유로 업그레이드하기를 기대하지 않기 때문에 당분간 2.2를 고수 할 것입니다.

누군가가이 문제에 대해 의견을 나눌 수 있기를 바랍니다.

는 다음에 플러그인을 업데이트하고 일했다 :

<plugin> 
    <!-- Run "mvn hibernate3:hbm2ddl" to generate schema --> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>hibernate3-maven-plugin</artifactId> 
    <version>${hibernate3.maven.plugin.version}</version> 

    <configuration> 
     <hibernatetool> 
      <annotationconfiguration propertyfile="src/main/resources/${hibernate.properties}" /> 
      <hbm2ddl update="true" create="true" export="false" 
        outputfilename="${hibernate.hbm2ddl.sqlfile}" format="true" 
        console="true" /> 
     </hibernatetool> 
    </configuration> 
</plugin>
