问题一:
问:项目图标报错,Problems 试图有一条错误显示“Java compiler level does not match the version of the installed Java project facet.” 。
答:这个是因为Facted Project 中的Java 版本设定与项目的Java 版本设定不一致。
如Drawing 1: Modify: Modify Faceted Project 中所示,这个时候项目的Java 的版本为5.0 。如果项目的Java Compiler 的设置如Drawing 2: Java C: Java Compiler 中所示的设置。就是会出现问题中所述的错误。修改的方式很简单,只要统一一下他们的设置。让他们保持一致就OK 了。
1 . u~p工程, 目录上显示红色X号, 在Problems中,显示:
Java compiler level does not match the version of the installed Java project facet.
: 根据翻译 是 编译器 与安装的jpf 不匹配:
但查看compile 为1.6.
而在buildPath中,Library / jre 也为1.6.
为什么呢?
百度一下=>
http://cai555.iteye.com/blog/468409 已解决:
//在项目上右键properties-->Project Facets可以更改项目编译级别
在 Java Compiler 可以更改jdk编译级别.
//
解决:
按照上边方法 查看原来 project Facets为1.4. 修改为1.6 OK.
总结: 对java project facet 不了解. 它与jre不是一回事.
