Ant中的Java编译错误：在注释中使用类文字

Question

I have the following Java annotation on a class (it's for a myBatis plugin):

@Intercepts({ @Signature(type = ResultSetHandler.class, method = "handleResultSets", args = (Statement.class)) })
public class MyResultSetHandlerPlugin implements Interceptor {
    //do stuff...
}

It compiles and works fine in Eclipse, but when trying to run an Ant build script, I get the following error:

[javac] C:CLIP_PoC\src\com\lmig\am\claims\clip\MyPResultSetHandlerPlugin.java:27: annotation value must be a class literal
    [javac] @Intercepts({ @Signature(type = ResultSetHandler.class, method = "handleResultSets", args = (Statement.class)) })
    [javac]                                                                                             ^
    [javac] 1 error

I've tried fully qualifying the classes used in the annotation, but that results in the same error. Any thoughts on what I'm doing wrong?

Thanks.

如果您尝试将项目数组作为注释参数传递，则需要使用花括号而不是括号来指示该项目是数组。

@Intercepts({ @Signature(type = ResultSetHandler.class, method = "handleResultSets", args = {Statement.class}) })
