Gradle deployment fails with "java.io.IOException: The filename, directory name, or volume label syntax is incorrect"

Hello, I’m trying to onboard a couple of new developers to get them working on our Java code, but I’m running into this error in Windows. All other Gradle commands work fine (clean project, clean dp, check dp, etc.), but our deployment command (dpDeployAll) fails. I followed the exact same setup process on 3 different Windows machines; the two machines running Windows 10 face this error, the machine running Windows 7 does not.

I’ve spent at least six hours looking into this unsuccessfully (cleaning project, rebuilding project, resyncing Gradle, reinstalling JDK, checking JAVA_HOME, deleting/reimporting project, etc.). I’m not a dev by training and have tapped out what I can do based on Googling similar issues. Can anyone help?

Hopefully it’s a quick answer for someone who actually knows what they’re doing. Thanks!

Here is the stacktrace:

$ gradle dpDeployAll -Phost=10.2.9.106 --stacktrace
:deploy:checkJavaVersion UP-TO-DATE
:deploy:compileJava UP-TO-DATE
:deploy:compileGroovy UP-TO-DATE
:deploy:processResources UP-TO-DATE
:deploy:classes UP-TO-DATE
:deploy:dpDeployAll

ChargeAdmin servlet version on 10.2.9.106 is 1.3.1

Edit: adding readme for dpDeployAll. all_production.txt lists all the individual packages (com.projectfw.mobi.whatever).

## dpDeployAll

Deploys the deployment packages specified in the `all_production.txt`
profile to the specified host.

The deployment packages will be retrieved from the `build/distributions`
subdirectory within the package directory for each package.  If multiple
deployment packages for a given package exist in this location, the one
with the highest version number will be used.

If a package does not already exist on the target host, it will be
deployed.

If a package already exists on the target host, but its version is different
than the highest local version, it will be replaced.

If a package already exists on the target host with an identical version
number to the highest local version, and the version contains the string
`dev` in its qualifier, it will be replaced no matter what.
For example: `3.1.2.dev`.

If packages exist on the device which are not specified in the package
profile, they will be uninstalled.

```
gradle dpDeployAll -Phost=<host>
```

This is because you pass backward slash(‘\’) in gradle-local.properties or any gradle file in which the server is defined.
It accepts only (‘/’) slash.
Example:- C:/Work/Project/MRI/Servers/Testing Server/liferay-ce-portal-7.4.3.80-ga80

Actually, you can also use backslashes in a properties file, but you have to double them, as a single backslash is the escape character in a properties file.
