[Native Image] Can not write to network drive

[Ferrarisrex]

Describe the Issue

it has the error of:
Error: Writing image to directory without write access N:\data\psdapp\target is not possible. Ensure the directory has write access or specify image path with write access.
it does have access, when i do the mvn -Pcompat package it does write new jar files to the directory
the drive is mounted using net use N: \address, and appears as such in file explorer
I can write to this directory outside of graalvm

test writes work just fine:

Maven itself can also access the network drive, just not graalvm

Using the latest version of GraalVM can resolve many issues.

• I tried with the latest version of GraalVM.

Is there a reason why you would want to build the native image on a Network drive? this is not a use case I've encountered before

[Karm]

For the record:

graal/substratevm/src/com.oracle.svm.driver/src/com/oracle/svm/driver/NativeImage.java

Line 1388 in b7571b8

if (!Files.isWritable(imageNamePathParent)) {

I have like 6 people working on the program, all on different computers, and this seemed like a logical solution

[fniephaus]

So it looks like Files.isWritable() can be unreliable on Windows network drives. Maybe a better check is to try and create a temp file?
