I'd like to get the GWT version from inside a linker (say the link()
method) which in client code can be done via GWT.getVersionI(), however,
nothing I've tried appears to work. You can't use the client version of
GWT as that leads to a runtime Java exception since the method getVersion()
cannot be found:
java.lang.UnsatisfiedLinkError:
com.google.gwt.core.client.GWT.getVersion0()Ljava/lang/String;
[java] at com.google.gwt.core.client.GWT.getVersion0(Native Method)
[java] at com.google.gwt.core.client.GWT.getVersion(GWT.java:191)
:
which is understandable since we're not in client code, but I also can't
use the ServerGwtBridge via something like:
ServerGwtBridge.getInstance().getVersion(), as that just returns the string
"unknown". Indeed it's hardcoded as "unknown" in the source so I'm not
sure what good it is - unless something else is supposed to inject a valid
version string. Finally, if I import the class
com.google.gwt.core.*shared*.GWT
and call GWt.getVersion() on that, then it will run (unlike when you try to
refer to the "client" package), but the result is null. Nice, right?
All I can think of at this point is using something like System.getenv() to
try to read GWT_HOME, but that seems wrong. Is there no working
getVersion() I can call?
