@olonho please~

[olonho]

do you use JDK 15?

[olonho]

for me ./gradlew :packageDmg produces meaningful DMG with the following JDK:

OpenJDK Runtime Environment AdoptOpenJDK (build 15.0.1+9)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 15.0.1+9, mixed mode, sharing)

[Sololo]

I use JDK 14

[olonho]

Please use JDK 15
