GWT source compile error

[Chandula Harasgama]

Hi. I'm trying to compile the current master of GWT from source but keep getting the following error. I'm on JDK 8 on a windows 7 PC.

The commands I tried were: ant, ant clean dist-dev, ant clean elemental dist-dev.

merge_codeserver:

     [echo] Merge gwt-dev.jar and gwt-codeserver.jar

      [jar] Building jar: C:\Users\chandulah\Desktop\gwt\trunk\build\out\gwt-dev-merged.jar

Thanks in advance for any help you could provide!

Hmmm maybe the ANT build holds the gwt-dev.jar open and thus Windows forbids overwriting the file with gwt-dev-merged.jar . I guess you need to either try changing the build file to make is work on Windows or use a Linux VM for now.
