Description

• I deleted the dev user directory and dev cache directory for NetBeans.

• I downloaded and installed Build #416 on Windows 10. 

• I selected Help > Check for Updates.

The installer very briefly displayed a screen stating that "the following plugins will be updated"...

Docker UI [1.1.4 -> 1.1.4]

IDE Platform [1.34 -> 1.34]

Local Tasks [1.26 -> 1.26] 

Note that both version numbers are the same in all three cases. See the attached screen shot installer1.png.

• Then a second screen replaces that almost immediately, stating Some plugins require Java Source Base to be installed. However, the only enabled button is Cancel. See the attached screen shot installer2.png.

• After clicking Cancel I am immediately prompted to Click here to make you IDE up to date. See the attached screen shot installer3.png. If I click the link in the balloon then the same scenario as described above is repeated, and I cannot update anything.

• I also face the same problem if I use alternative GUI navigation to  attempt to do the updates:

[1] Help -> About  then click the Updates available link.

[2]Tools -> Plugins -> Updates -> Check for Updates

Note that I have downloaded many other builds (most recently #398) and not encountered this problem. I have assigned this issue Major priority since I can't apply updates, but please downgrade if appropriate.
