Question
NetBeans do not accept my code. Why? See the pic.
Solution
You need to change the code from
package org.demo.myfilter;
import org.demo.textfilter.TextFilter;
@ServiceProvider(service=TextFilter.class)
public class UpperCaseFilter implements TextFilter {
public String process(String s) {
return s.toUpperCase();
}
}
into
package org.demo.myfilter;
import org.demo.textfilter.TextFilter;
import org.openide.util.lookup.ServiceProvider;
@ServiceProvider(service=TextFilter.class)
public class UpperCaseFilter implements TextFilter {
public String process(String s) {
return s.toUpperCase();
}
}
Note: You can leverage the Fix Imports item from the Source menu (CTRL-SHIFT-I/Clover-SHIFT-I) to take care of the second one automatically, if you have declared the dependeny between your module and the NetBeans platform Utilities API module
OTHER TIPS
You need to import the annotations you're using.
E.g, import org.whatever.package.contains.ServiceProvider;
import {package}.ServiceProvider;
Perhaps you are missing an import. Can you import "ServiceProvider"? It's hard to know for sure without know more about your project setup, but that's my first guess.
