launch4j: "The process cannot access the file..."

Question

I just upgraded to Win 7, and now my launch4j setup isn't working anymore.

Clues?

Using the launch file below, I get these errors:

 [exec] launch4j: Compiling resources
 [exec] launch4j: Linking
 [exec] launch4j: Wrapping
 [exec] launch4j: H:\Documents\QueryAnalyzerFaker\QueryAnalyzerFaker\.\batchexport.exe (The process cannot access the file because it is being used by another process)
 [exec] launch4j: java.io.FileNotFoundException: H:\Documents\QueryAnalyzerFaker\QueryAnalyzerFaker\.\batchexport.exe (The process cannot access the file because it is being used by another process)

Here's the launch configuration

<launch4jConfig>
  <dontWrapJar>false</dontWrapJar>
  <headerType>console</headerType>
  <jar>.\batchexport.jar</jar>
  <outfile>.\batchexport.exe</outfile>

Answer 1

The problem appears to be caused by some interference between the synchronization service for the destination drive (network drive) and launch4j.

I resolved it by building on the local c: drive, then adding an Ant target for copying the output to the desired folder on the network drive.
