Any ideas how to get around this?

Answer 1

下载ADT插件 ，将所有文件夹（功能，插件，Web ...）解压缩并复制到Eclipse安装文件夹中。

Answer 2

如果您使用窗口7而不是以管理员身份运行

Answer 3

The only solution I found was to reinstall Eclipse from scratch. This is actually fairly easy, since all you have to do is unzip the package.

So, I took the opportunity to upgrade to Eclipse Indigo at the same time.

Answer 4

I really can't do fresh install as my Eclipse is fully loaded with other features that I use in my projects. And migrating features from existing Eclipse install to new install is painful in my experience (not considering if it will work).

So I just unpacked the ADT zip file into the Eclipse install then it worked.

Answer 5

I had the same issue and I tried copying all the files from ADT PLUGIN , re-installed eclipse but none of them seemed to help. Only updating eclipse (Help > Check for Updates) solved the issue.

BNW, STACK OVERFLOW has the same discussion.

Answer 6

Just unzip the ADT and copy the contents to appropriate folders in eclipse installation. Restart Eclipse. The issue will be solved.

Answer 7

If you have come to this old thread while trying to upgrade your Eclipse Helios SDK to Lollipop, note the dependencies:

ADT 23.0.4 (October 2014)

Your existing Eclipse installation must meet these requirements:

• Eclipse 3.7.2 (Indigo) or greater
  • Note: Eclipse 3.6 (Helios) is no longer supported with the latest version of ADT.
• Eclipse JDT plugin (included in most Eclipse IDE packages)
• JDK 6 (JRE alone is not sufficient)
• Not compatible with GNU Compiler for Java (gcj)

I upgraded to Eclipse Luna and these errors did not reappear.

Answer 8

Error messages can be surprisingly useful. The error message says you have a conflicting dependency. If it were my box I'd probably uninstall all instances of Eclipse, then install the one you want and see if that works.
