Specified VM install not found: type Standard VM, name jre7
This is a preferred way tell projects which JDK container to use, especially true if two or more devs are using the same version controlled eclipse project folder.
Window/Preferences/Java/Installed JREs
List one or more JDKs installed on your computer. Eclipse defaults name to jdk1.X.X_XX you should keep it as is. Never link project build settings directly to use these names.
Window/Preferences/Java/Installed JREs/Execution Environments
List of common jvm environments such as JavaSE-1.6 and JavaSE-1-7 names. Click rows and choose jre instance on the right side panel. These names are common and all team members should already have them in Eclipse installation.
Step 1: This is where you may accidentally have nothing chosen if JREs were uninstalled or names changed in InstalledJREs setting. You may get
Specified vm install not found error dialog.
Step 2: Choose 2nd mouse on build.xml file/Run As/Ant Build... popup menu entry. Click on JRE tab and choose execution environment. This may have obsolete value from the previous jdk values.
Project Properties/Java Build Path/Libraries
Add Library.../JRE System Library/(x)Execution environment
Choose execution environment to be used for this project. Team members may not have exact _XX jdk build but they can use the same version controlled eclipse project settings. Execution environment mapping hides user specific details.
- Right Click on build.xml
- Go to "Run As" >> "External Tools Configurations..."
- It shall open new window
- Go to JRE tab
- Select proper JRE if missing (sometimes jre tabs shows error mark on that.)

It happened for me after Un-installing Java and installing new version.
All I have to do is in eclipse open Installed JREs from
Windows --> Preferences --> Java --> Installed JREs
Then Add new JRE information. Details can be found here
In my case it happen as I have changed my JRE.
Solution :
Right click on your ant script > Run as > External tool configurations... > Go to JRE tab > select JRE
Hope this help.
