Maven：编译 package-info.java 到 package-info.class？
[英]Maven: Compiling package-info.java to package-info.class?
问题描述
I have package-info.java in my package, Hibernate wants it for some features (programatic entity scanning).
我的 package 中有 package-info.java，Hibernate 想要一些功能（程序实体扫描）。
However, mvn package does not result in package-info.class being in classes/ thus not in the artifact.但是， mvn package不会导致package-info.class在classes/因此不在工件中。
How can I force that happening?我怎样才能强迫这种情况发生？
mvn -v

Works correctly in Maven 3;在 Maven 3 中正常工作； don't know about 2. Is it possible that the package declaration in package-info.java is missing or wrong?不知道 2. package-info.java 中的 package 声明是否可能丢失或错误？

The error was that the package-info.java must have any annotation with Retention=RUNTIME to compile into a class.错误是 package-info.java 必须有任何带有Retention=RUNTIME的注释才能编译成 class。 Otherwise, JDK 6 omits it.否则，JDK 6 会忽略它。
I used @Deprecated which is the only one in Java SE (and I didn't want to introduce an annotation just because of that).我使用@Deprecated ，它是 Java SE 中唯一的一个（我不想仅仅因为这个而引入注释）。
@Deprecated
