当我在下面添加此代码pom.xml以支持Querydsl时

<plugin>
  <groupId>com.mysema.maven</groupId>
  <artifactId>apt-maven-plugin</artifactId>
  <version>1.0.6</version>
  <executions>
    <execution> 
      <goals>
        <goal>process</goal>
      </goals>
      <configuration>
        <outputDirectory>target/generated-sources/java</outputDirectory>
        <processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
      </configuration>
    </execution>
  </executions>
</plugin>

使用Eclipse构建时出现此错误.我认为它与classpath和JDK jar有关系

You need to run build with JDK or have tools.jar on the classpath.
If this occures during eclipse build make sure you run eclipse under  JDK as well 
(com.mysema.maven:apt-maven-plugin:1.0.6:process:default:generate-sources)

.classpath:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" output="target/classes" path="src">
        <attributes>
            <attribute name="optional" value="true"/>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="con" path="org.eclipse.jst.server.core.container/org.eclipse.jst.server.tomcat.runtimeTarget/Apache Tomcat v8.0">
        <attributes>
            <attribute name="owner.project.facets" value="jst.web"/>
        </attributes> …
