java - The import org.omg .CORBA cannot be resolved when use plexus-compiler-eclipse for compiling -

our project developed maven on jdk 1.7.0_17, imported org.omg.corba.intholder in code , run "mvn clean install" gives me errors "the import org.omg .corba cannot resolved"

i don't know why, can find class file can not resolved in %java_home%\jre\lib\rt.jar

my pom file configured below:

<plugin>     <groupid>org.apache.maven.plugins</groupid>         <artifactid>maven-compiler-plugin</artifactid>         <version>3.1</version>       <configuration>           <compilerid>eclipse</compilerid>         <source>1.7</source>         <target>1.7</target>         <compilerversion>1.7</compilerversion>         <proceedonerror />         <optimize>true</optimize>                   </configuration>      <dependencies>           <dependency>               <groupid>org.codehaus.plexus</groupid>               <artifactid>plexus-compiler-eclipse</artifactid>               <version>2.2</version>           </dependency>       </dependencies>   </plugin>
