Running GWT SuperDevMode in IDEA on Win8

Question

I am trying to configure my GWT project to run in SuperDevMode and experience severe problem during server run time.

So, I have working "regular" devMode configuration in Intellij IDEA. Created a new GWT configuration in app-servers list. Set the following values:

[Checked] Super Dev Mode

VM options: -Xmx512m -XX:MaxPermSize=384M

Dev Mode parameters: -bindAddress 0.0.0.0 -port 1234 -workDir d:\projects\myApp\SDV\ -src d:\projects\myApp\src\main\java com.app.MyApp

Made changes to my project's build xml file adding the lines in the end of file:

    <add-linker name="xsiframe"/>
    <set-configuration-property name="devModeRedirectEnabled" value="true"/>
    <!-- enable source maps -->
    <set-property name="compiler.useSourceMaps" value="true" />

Here is the console output on this config run:

workDir: d:\projects\myApp\SDV
deleting: d:\projects\myApp\SDV\com.app.MyApp\compile-1
binding: user.agent=safari
binding: compiler.useSourceMaps=true
binding: locale=en

Process finished with exit code 1

I suspect it maybe Win8 file access permissions problem: cannot create the directory because it wasn't deleted successfully. Both lines in the log above that have this text:

deleting: d:\projects\myApp\SDV\com.app.MyApp\compile-1

are of red color in IDEA (if that has any special meaning).

I unchecked READ_ONLY checkbox in the properties of for the work folder in file explorer, and also run idea64.exe as Admin. Should I somehow run this codeserver compiler "as admin" too? Is it possible?

Also it may be a configuration issue, if it is and somebody can see it from the details below - I would really appreciate the help. Thanks in advance!

UPDATE

Running the superDevMode config with parameter "-noprecompile" gives the same results:

workDir: d:\projects\myApp\sdv
deleting: d:\projects\myApp\sdv\com.app.MyApp\compile-1
Module setup completed in 865 ms
deleting: d:\projects\myApp\sdv\com.app.MyApp\compile-1
[ERROR] unable to create directory: d:\projects\myApp\sdv\com.app.MyApp\compile-1
com.google.gwt.core.ext.UnableToCompleteException: (see previous log entries)

    at com.google.gwt.dev.codeserver.CompileDir.create(CompileDir.java:93)
    at com.google.gwt.dev.codeserver.Recompiler.makeCompileDir(Recompiler.java:267)

So, definitely looks like file access problem (delete doesn't do its job?). Javadoc to CompileDir.create() method says: "Creates a new compileDir directory structure. The directory must not already exist, but its parent should exist." Seems that it already exists.

Ok, so this is fixed now in GWT 2.7.0 by GWT team. https://code.google.com/p/google-web-toolkit/issues/detail?id=8619

Runs well, even though I can notice the message in the IDE console:

[WARN] unable to delete 'C:\Users\me\AppData\Local\Temp\gwt-codeserver-1341369077945982663.tmp\com.bla.MyAPP\compile-1' (skipped)
[ERROR] unable to create directory: C:\Users\me\AppData\Local\Temp\gwt-codeserver-1341369077945982663.tmp\com.bla.MyAPP\compile-1
Loading Java files in com.bla.MyAPP.

after printing this the IDE continues to run the app server.

Resolving the issue.

I think your configuration is correct. I am using the same parameters (with another portnumber) on my Mac and it works as expected.

The red color of the text:

deleting: d:\projects\myApp\SDV\com.app.MyApp\compile-1

is normal and indicates no problem.

I am not familiar with Windows 8, but would think, that you don't need to run idea.exe with admin rights. I think, uncheck the read-only checkbox should solve your problems.

Another way should be, that you create your workDir directory with Intellij.

File -> New -> directory

(That's what I did).

I also found that if you are converting your project from GWT 2.6.0 to 2.7.0, you should delete your 2.6.0 run configuration and setup a new one with GWT 2.7.0 defaults.
