java - 如何在 Eclipse 中设置编译器选项 'processor'？

Question

我尝试按照以下说明配置 DataNucleus 增强器:

If using Eclipse you need to edit your project properties. Go to Java Compiler -> Annotation Processing and enable the project specific settings and enable annotation processing. Then go to Java Compiler -> Annotation Processing -> Factory Path , enable the project specific settings and then add the following jars to the list: datanucleus-enhancer.jar , datanucleus-core.jar , jdo-api.jar and asm.jar and set the compiler argument processor to org.datanucleus.enhancer.EnhancerProcessor

一切都很棒，直到我看到粗体文本。我似乎无法理解他们的意思。有人可以扩展这句话以使其对新手更友好吗？ :)

我相信这是在:

Java Compiler
  Annotation Processing
    => Process options
    key= processor
    value=org.datanucleus.enhancer.EnhancerProcessor

这是您可以输入此类参数的唯一位置，并且它符合您在问题中提到的关于 Automatic invocation from javac (annotated classes only) 的 DataNucleus 编译指令。 :

If using Eclipse you need to edit your project properties.
Go to Java Compiler -> Annotation Processing and enable the project specific settings and enable annotation processing.
Then go to Java Compiler -> Annotation Processing -> Factory Path , enable the project specific settings and then add the following jars to the list:

• datanucleus-enhancer.jar,
• datanucleus-core.jar,
• jdo-api.jar and
• asm.jar

and set the compiler argument processor to org.datanucleus.enhancer.EnhancerProcessor

事实上，这些说明适用于带注释的类，因此它们符合此“注释处理”设置的条件。
