Re: [GWT] [ERROR] Hint: Check that your module inherits ''

Tiberiu, the fact that it works in Eclipse strongly suggests to me that the ant classpath is different from the eclipse project classpath. That different configuration will lead to different results. This error is typically indicative of some other error happening (typically classpath related) - double check that, and add the "-strict" argument to the Compiler invocation to make sure you see any earlier errors as well (if any).

Hello everyone,

I just upgraded to GWT 2.10.0 from 2.8.1 and I receive the same error when compiling through an Ant build.

The code and scripts are identical and is compiling just fine with Java 1.8, GWT 2.8.1 and Eclipse 4.17. However with Java 13 or 17, GWT 2.10.0 and Eclipse 4.28 gives the error. Although in the second configuration it compiles successfully through the Eclipse GWT plugin it does not compile using the Ant build. But the GWT module is the same...

What am I missing?

Thanks you,

GWT *runs* on JDKs from 8 to 17; you can however only compile Java 11 –at most– source files (depending on -sourceLevel).

When facing that kind of error, make sure you run with -failOnError (or its older name: -strict), and possibly use a more verbose -logLevel.

Hello here.
I would like to react for this threat. Would at this time (2022) gwt supports java 12?
For I am experiencing the error mentioned above.
Thanks in advance.

I don't believe GWT supports Java 12 yet.  I'd recommend just using Java 8.

And you might want to use the latest GWT version (2.8.2).
