Demo Project is busted #113

Closed mfreeman-xtivia closed 3 years ago

mfreeman-xtivia commented 3 years ago

Have tried to compile the demo project (vue-gwt-demo) OOB with Maven 3.8.1 and 'mvn package' dies a miserable death.

Fails both on straight Windows and UbuntuWSL2

Hi!

I just tried on my side and it seem to work. My configuration:

➜  vue-gwt-demo git:(master) java -version 
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)
➜  vue-gwt-demo git:(master) mvn -version   
Apache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)
Maven home: /usr/local/Cellar/maven/3.8.1/libexec
Java version: 1.8.0_211, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home/jre

Steps I followed:

Do you have details of the error you are encountering?

Did the git clone, then mvn clean install. Receive this error:

Thank you for the fast reply! Hum this is weird, which version of Java are you using? This might help me reproduce 👍

Indeed I just tried and I do get an NPE at build time with OpenJDK 11. Not sure if the problem is 11 or OpenJDK VS Oracle. If you want to have a try, Oracle Java 8 should work, in the meantime I'll try to see what's missing on it for it to run on OpenJDK 11, I'm pretty sure it used to work there 🤔 .

adrienbaron commented 3 years ago

Ok, good news the tests are working on OpenJDK 11. They build an actual app and test inside a headless broaser so I'm confident it does work:

[INFO] HeadlessChrome 91.0.4472 (Mac OS X 10.15.7): Executed 229 of 229 SUCCESS (1.725 secs / 0.096 secs)
[INFO] TOTAL: 229 SUCCESS

However I haven't figured out why the demo project isn't working yet, still looking into it.

adrienbaron commented 3 years ago

@mfreeman-xtivia Ok figured it out, demo project was using an old version of Vue GWT that didn't support Java 11 🤦 . The new version doesn't rely on Nashorn anymore (that got booted from Java) and uses Rhino instead 👍

I just pushed a commit to master, it should work now 👍 ! Thanks again for the report!

mfreeman-xtivia commented 3 years ago

Works perfectly now!!! Thank you
