我正在使用hibernate-jpamodelgen使用maven生成元模型类。
当我运行 mvn clean package时 ,它运行正常,没有任何问题。但是,如果我第二次运行 mvn软件包 (没有清理),则会收到以下异常:

环境 :
JDK version : 1.8.0_51 Maven version : 3.3 Hibernate version : 4.3.7.Final
我的pom.xml中的代码段:
<dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-jpamodelgen</artifactId> <version>4.3.7.Final</version> <scope>provided</scope> </dependency>
找到答案!…
这是 3.2 和 3.3 版本的 maven-compiler-plugin中的错误 。
当我第二次运行“ mvn package ”时,先前生成的源目录会在 generate-source 阶段之前添加到源路径,这会导致此 解析器异常 。
切换回maven-compiler-plugin 的旧版本( < 3.2) 可解决 此问题。
请注意,在 maven-compiler-plugin的* 3.0 和 3.1 版本中, 增量编译 被 破坏 了。因此,我更喜欢切换 2.5.1 版本的maven-compiler-plugin。 ***
