Java compiler level does not match the version of the installed Java project fac

周5 要打war包传到服务器，可是我本地是1.6的环境，服务器是1.5，所以我要改本地，结果非常不顺利，搞到晚上7点多也没搞定，今天早上 google 一下 找到了这边文章，很好很强大。

ps：我之前 只是 把1.5的包引进（这步 现在看是 不必的），然后 java compiler 选 1.5，报错。

=========================================================================

问题现象：项目图标报错“Java compiler level does not match the version of the installed Java project facet.”。


分析原因：这个是因为Project Facets中的Java版本设定与项目的Java版本设定不一致。

解决方法：（依据ECLIPSE自带的帮助）

Changing the version of a facet

You can change the version of a facet in a J2EE project by editing the facets for the project.

Changing the Java compiler version of a J2EE project involves changing the version of the Java facet. See Changing the Java compiler version for a J2EE project.

1. In the Project Explorer view, right-click the project and then click Properties.

2. In the Properties window, click Project Facets. The Project Facets page lists the facets in the project.

3. Click Add/Remove Project Facets.

4. In the Add/Remove Project Facets window, click the facet you want to change to select it.

5. Select the version of the facet from the drop-down box next to the facet's name.

6. Click Finish.

7. Click OK.
