eclipse3.7 INDIGO安裝adt 缺少條目時的解決辦法

eclipse3.7 INDIGO在安裝adt的時候

也就是，add again the ADT location http://dl-ssl.google.com/android/eclipse/的時候

出現如下類似錯誤

Cannot complete the install because one or more required items could not be found.

需要多做一步

參考http://stackoverflow.com/questions/4249695/adt-requires-org-eclipse-wst-sse-core-0-0-0-but-it-could-not-be-found

1. help->install new software

2. click on "available software sites"

3. select all entries (CTRL-A) and remove them

4. add new entry at location http://download.eclipse.org/releases/indigo/

5. now add again the ADT location http://dl-ssl.google.com/android/eclipse/
