Can't get samples to work

[stekar]

I've been struggling in two days to start using SmartGWT LPGL. Setup: smartgwt-12.1p, GWT 2.9.0 ANT 1.10.9 Java JDK 1.8.241
It is impossible to get the HelloWorld or the Showcase samples through the GWT compiler. I get hundreds of errors. The only thing I've changed in the build.xml is the Java version to 8 and increased JVM heap limit. Output:

libs:

javac:

and so on.


I have also tried using IntelliJ IDEA 2020.2 without any luck. Using IntelliJ I have added the two smartgwt jars to our existing GWT application and changed the *.gwt.xml. Added a SmartGWT widget. The compilation now runs OK. But the application now crashes in Runtime at startup:

We agree that these projects need more memory configured, but other than that, we're not seeing the problems you report building SGWT LGPL with ant. Using the SGWT LGPL build dated 2021-02-23, we made the following adjustments to the build.xml for the HelloWorld-2.0 and Showcase projects:

  source="1.8" target="1.8" nowarn="true"

and

  <jvmarg value="-Xmx1G"/>

(for both "gwtc" and "hosted" targets).

Then running "ant war" built things with no issue.

We ran this on OpenSUSE 15.2 Linux with:

• GWT 2.9.0
• Ant 1.10.7
• JDK8 261

and on MacOS Catalina (10.15.7/19HS24) with:

• GWT 2.9.0
• Ant 1.10.5
• JDK8 191

You're using a Mac, right? The only thing that stands out is your ant version. You might try using an earlier version of ant. Also make sure that you have plenty of OS memory and disk space left during the build.

As far as a GUI, we recommend Eclipse. For details, take a look at the help topics Debugging and Troubleshooting.
