java - 在 Eclipse 中为项目build设置 JRE

Question

我发现在Eclipse中选择执行环境有几个选择:

所有这些选择意味着什么？我看到它们都与java版本有关。但是 CDC 和 OSGi 是什么意思呢？ (unbound) 是什么意思？

Answer 1

整个列表是可用的执行环境。

这是完整的列表

https://wiki.eclipse.org/Execution_Environments#Standard_Execution_Environments

EE Name Description OSGi/Minimum-1.0 OSGi Minimum Execution Environment 1.0 - This is a subset of the J2ME Foundation 1.0 class libraries defined by OSGi to be the base for framework implementations.

OSGi/Minimum-1.1 OSGi Minimum Execution Environment 1.1 - This is a subset of the J2ME Foundation class libraries defined by OSGi to be the base for framework implementations.

CDC-1.0/Foundation-1.0 J2ME Foundation 1.0 - With the exception of some MicroEdition IO classes, Foundation 1.0 is a subset of J2SE 1.3.

CDC-1.1/Foundation-1.1 J2ME Foundation 1.1 - With the exception of some MicroEdition IO classes, Foundation 1.1 is a subset of J2SE 1.4.

未绑定(bind)意味着，该环境将该环境添加到您的 eclipse 中，并且 eclipse 不再记住它的路径。您需要重新编辑并提供位置。
