GWT is broken in version 1.7.0

Looks like the cause is the new GdxFileSystem. Here is the output that I get when trying to compile for GWT:

Ok, looks like there are a few issues on GWT:

As @MobiDevelop said on the irc channel, we should add AbsoluteFileHandleResolver and LocalFileHandleResolver to the libgdx GWT module.
Add missing FileHandle constructors to the libgdx GWT module.
StringTokenizer.countTokens() is not supported by GWT. This must be fixed in gdx-ai, I guess

Answer 2 · 2016-01-09T00:05:15.000Z

Now items 1 and 2 should be fixed by this commit and this commit respectively

Answer 3 · 2016-01-09T13:59:11.000Z

Just realized that StringTokenizer is emulated by the libgdx gwt backend, see https://github.com/libgdx/libgdx/blob/master/backends/gdx-backends-gwt/src/com/badlogic/gdx/backends/gwt/emu/java/util/StringTokenizer.java

We might simply update that class in order to support countTokens.

Hi! I have this problem. How can I update my project to get your fixes?

Answer 5 · 2016-04-07T22:36:34.000Z

@AlexanderSopov
Update to gdx-1.8.0.
If you use gradle, just change the gdx-ai version in your build.gradle.

Answer 6 · 2016-04-08T01:23:40.000Z

@davebaol hi! I did do just that. In the build.gradle in the root folder of the project I changed the following thing:

allprojects{
[...]
ext{
appName = "SharpShooter"
gdxVersion = '1.8.0'
roboVMVersion = '1.12.0'
box2DLightsVersion = '1.4'
ashleyVersion = '1.7.0'
aiVersion = '1.8.0' * >>it was 1.7.0 before<<*
}
}

and I still get the same error. Did I miss something? :(

Answer 7 · 2016-04-08T07:42:00.000Z

Looks like you have not run gradle to refresh depencencies and rebuild your project.
You can do it either from inside your IDE or through command line.

Answer 8 · 2016-04-08T11:18:46.000Z

@davebaol actually I got it working by changing ai-version to 1.6 so I doubt that refreshing dependencies will help, but I will try. Thanks a lot! :)

Answer 9 · 2016-04-08T11:23:09.000Z

Yes, I did gradle build --refresh-dependencies and it did not help circumvent the issue. I still get an error with the exact error as the OP in this thread.

Answer 10 · 2016-04-08T11:50:11.000Z

Try using these versions

gdxVersion = '1.9.2'
aiVersion = '1.8.0'

I had to change StringTokenizer emulation in libgdx 1.9.0, see the commit linked in #59 (comment)

Answer 11 · 2016-04-08T14:12:07.000Z

@davebaol thanks man! That solved it! I had to make some changes to the htmlLauncher but that wasn't hard. 💃
