Failed to create the part's controls in Eclipse with Salesforce

Question

Answer 1

In ecllipse, every file types has some associated default formats and one of the default format set to the particular file type.

You can see this in General -> Editors -> File Associations-

This issue generally occurs when we open any file in the format which is not the default format of the particular types.

I got same issue when I opened one of the Java file in text format in ecllipse and then I started getting the same issue. After research, I observed that AspectJ/Java Editor was setting as default. After reset it to Java Editor, the problem got resolved.

Steps : 1. General -> Editors -> File Associations- 2. Select the content type and choose the default format for it. 3. Restart the ecllipse.

In general, it is some default file format that set in ecllipse causing the same issue.
