我正在使用 Ant 进行构建，我遇到了这些错误:

错误与我正在使用的注释有关。 我需要做什么来修复此 Ant 构建以编译我的类注释？

最佳答案

看起来您的注释数组中有尾随逗号，javac 将其视为非法 - 与“正确”数组不同。 (有一个 bug in eclipse 不报告这些。)

删除结尾的逗号，例如:

@MessageDriven(activationConfig =
{ @ActivationConfigProperty( ... ),
  @ActivationConfigProperty( ... ),
  @ActivationConfigProperty( ... ),
  @ActivationConfigProperty( ... ) // no comma here
} );

关于java - 注释表达式的非法开头，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/4883387/
