Errors in com/google/gwt/emul/java/lang/String.java

[Teletin Alin]

Hi all,

I have the following error at compilation:

Errors in com/google/gwt/emul/java/lang/String.java

[INFO]             [ERROR] Line 165: 'String.NativeFunction String.getFromCharCodeFunction()' has invalid name 'String.fromCharCode'.

[INFO]             [ERROR] Line 165: 'String.NativeFunction String.getFromCharCodeFunction()' has invalid namespace '<window>'.

[INFO]             [ERROR] Line 757: 'String.NativeString' has invalid namespace '<window>'.

[INFO]       [ERROR] Compiler returned false

The pom.xml versions for gwt:

<gwt.maven.plugin.version>2.8.0-rc2-patched</gwt.maven.plugin.version>

<gwt.version>2.8.0-rc3</gwt.version>

I search for the issue and there are only 2 relevant discussions:

https://groups.google.com/forum/#!topic/Google-Web-Toolkit-Contributors/4IY_L0Hj1cU

and

https://github.com/gwtproject/gwt/issues/9423 (I think the commit from here is causing the issue).

But I don't get from those discussions how to fix the issue.

Can you please help me?

Thank you,

Alin T.

The problem is that you have a mix of rc2 and rc3 libs in your classpath, and this is because org.codehaus.mojo:gwt-maven-plugin itself brings GWT dependencies (with the same version as the plugin, as a convention).

See http://gwt-maven-plugin.github.io/gwt-maven-plugin/user-guide/using-different-gwt-sdk-version.html; or use rc3 of the plugin too.

I want to confirm that having 

<gwt.maven.plugin.version>2.8.0-rc3</gwt.maven.plugin.version> (used for org.codehaus.mojo:gwt-maven-plugin)

<gwt.version>2.8.0-rc3</gwt.version>

solved the isue.

Thank you.
