The menu options for "Run Main Project" and "Debug Main Project" are disabled for Spring Boot applications. See attached screen recording (note also that the menu does not update automatically).
Steps to reproduce:
1) Generate a demo Spring Boot Gradle project here:
2) Open Project in Netbeans. Menu items are disabled.
1) Use the "bootRun" task as found in the Navigator panel.
or 2) Modify build.gradle to add in the application plugin and mainClassName variable. This causes NetBeans to add a "run" task and enables the menu.
