使用links方式安装Eclipse插�g

飞翔天�� — Sun, 01 Mar 2009 02:23:00 GMT

现在假设我的eclipse安装目录�?/span>D:\eclipse�Q�待安装插�g目录�?/span>D:\plug-in �Q�我��要安装LanguagePackFeature�Q�语�a�包）�?/span>emf-sdo-xsd-SDK�?/span>GEF-SDK�?/span>Lomboz�q�四个插件�?/span>

先把�q�四个插件程序全部放�?/span>D:\plug-in目录里，分别解压。如Lomboz3.0.1.zip解压�?/span>Lomboz3.0.1目录�Q�这个目录包含一�?/span>plugins目录�Q�要先在Lomboz3.0.1目录中新��Z��个子目录eclipse�Q�然后把plugins目录�U�d��到刚建立�?/span>eclipse目录中，即目录结构要是这��L��Q?/span>D:\plug-in\Lomboz3.0.1\eclipse\plugins�?/span>

Eclipse ��会到指定的目录下去查找 eclipse\features 目录�?/span>eclipse\plugins 目录�Q�看是否有合法的功能部�g和（或）插�g。也��是��_��目标目录必须包含一�?/span> \eclipse 目录。如果找刎ͼ�附加的功能部件和插�g在运行期配置是将是可用的�Q�如果链接文件是在工作区创徏之后��d��的，附加的功能部件和插�g会作为新的配�|�变更来处理�?/span>

其它压羃文�g解压后若已经包含eclipse\plugins目录�Q�则不需要徏�?/span>eclipse目录�?/span>

然后�?/span> eclipse安装目录D:\eclipse目录中徏立一个子目录links�Q�在links目录中徏立一�?/span>link文�g�Q�比�?/span> LanguagePackFeature.link�Q�改文�g内容为　path=D:/plug-in/LanguagePackFeature　卌��?/span>link文�g要对应一个刚解压后的插�g目录�?/span>

说明�Q?/span>

1. 插�g可以分别安装在多个自定义的目录中�?/span>

2. 一个自定义目录可以安装多个插�g�?/span>

3. link文�g的文件名及扩展名可以取�Q意名�U�ͼ�比如ddd.txt�Q?/span>myplugin都可以�?/span>

4. link文�g�?/span>path=插�g目录�?/span>path路径分隔要用\\或是/

5. �?/span>links目录也可以有多个link文�g�Q�每�?/span>link文�g中的path参数都将生效�?/span>

6. 插�g目录可以使用相对路径�?/span>

7. 可以�?/span>links目录中徏立一个子目录�Q��{�U�L��时不用的插�g到此子目录中�Q�加�?/span>eclipse启动�?/span>

8. 如果安装后看不到插�g�Q�把eclipse 目录下的configuration目录删除�Q�重启即可�?/span>
