Gradle-Build schlägt mit Java IOException fehl

Question

Ich erhalte die folgende Fehlermeldung, wenn ich versuche, die Datei gradle.bat oder einen anderen Gradle-Befehl auszuführen (z. B. gradle -version).

FAILURE: Build failed with an exception.

* What went wrong:
java.io.IOException: The filename, directory name, or volume label syntax is incorrect

Gradle-Version: 4.10.2

JDK: 1.8.0_261

Betriebssystem: Windows 10 (x64)

Was könnte möglicherweise schief gelaufen sein?

PS: Ich habe das auch mit einer neueren Gradle-Version (6.6.1) versucht. Es wurde ein ähnlicher Fehler generiert.

Gelöst ist das Problem einfach durch die GRADLE_USER_HOME Umgebungsvariable unter Hinzufügen von Benutzervariablen anstelle von Systemvariablen .
