產生的原因：

　　引用了本地jar包導致

pom.xml

<dependency>
     <groupId>com.abc</groupId>
     <artifactId>toolbox</artifactId>
     <version>4.5.1</version>
     <scope>system</scope>
     <systemPath>${basedir}/../lib/com.abc.toolbox-4.5.1.jar</systemPath>
</dependency>

解決方法：

　　將 basedir 修改為 pom.basedir

<dependency>
     <groupId>com.abc</groupId>
     <artifactId>toolbox</artifactId>
     <version>4.5.1</version>
     <scope>system</scope>
     <systemPath>${pom.basedir}/../lib/com.abc.toolbox-4.5.1.jar</systemPath>
</dependency>
