I've changed tool collection in Tools > Options but my project is still using the old tool collection. Why didn't it use the new one?
The default tool collection is used at project creation. To change the tool collection for a project later, open the project properties and change the Tool Collection (Compiler Collection in NetBeans 5.5.1, 6.0 and 6.1) property there.
Right-click the project name, select Properties, select Build category, and select a Tool Collection.
Applies to: NetBeans 5.5.1 and later
