Exception on fresh installation

[olehlong]

Hello. I've installed latest Eclipse (Mars.2 Release (4.5.2)) and latest DDT (0.14.1.v201602151533). When I'm choosing a package from autocomplete on import I always get an exception. Or even when I'm finishing typing package name. app.d - app file types.d - lib file

Also, according to the installation instruction, it should install DLTK automatically. But it doesn't. After installing DDT and using autocompletion I get an exception:

master, 0.14.0, 0.13.1, 0.12.1 with Mars.2 - crashes without any error in logs (maybe I need to enable debug mode before building). 0.14.1 with Neon - crashes with exception: java.io.FileNotFoundException: /icons/view16/ddt_persp.png 0.14.1 with Mars.1 - crashes with empty log file, after installing dltk it was automatically upgraded to Mars.2 :(

I don't know what to do anymore.

[bruno-medeiros]

Ok, first of all, DLTK is no longer a dependency of DDT, it hasn't been for a while now. It was mentioned in the Installation page, but that was an error (I've corrected it now). Can you try again with a fresh installation, and a new workspace? And send me a screenshot of the editor/IDE with what you have just before the "org.eclipse.swt.SWTException: Widget is disposed" error occurs.

[olehlong]

I'm not sure if it's ddt problem anymore, but maybe you can help somehow. Here is video https://vid.me/MqoK

[bruno-medeiros]

The error message indicates the JVM itself seems to have crashed. Maybe try a newer JVM and see if that helps? Otherwise, I'm at a loss as to what could be causing this. The crashes seem random.

[olehlong]

I've tried oracle 8, openjdk 8 already. Same behavior. On oracle 9 eclipse doesn't even start, it shows that error window right after clicking on eclipse. Thanks anyway. I'll have to switch to another ide :(

[olehlong]

Also I got:

>  ------ DTool engine started ------ 
Could not start DDT because Java version is: -1
Version 8 is required

with oracle 9 (but in docs it's 8 or later)

But ddt starts. Still get same jvm error though.

[bruno-medeiros]

Can you try installing DDT with just the Eclipse Platform Runtime Binary: http://archive.eclipse.org/eclipse/downloads/drops4/R-4.5-201506032000/#PlatformRuntime ?

[olehlong]

It doesn't start http://pastebin.com/d8Ys3fAD I'll try java 8.

[olehlong]

Java 8 - save error
