CLASSPATH is being set to the literal string \"\", which is not a valid path. This value is later passed through cygpath and also included in the Java invocation, which can break the wrapper on Cygwin/MSYS environments. Set CLASSPATH back to the wrapper JAR path (e.g., $APP_HOME/gradle/wrapper/gradle-wrapper.jar) or remove CLASSPATH entirely if switching to java -jar.

Suggested change

	CLASSPATH="\\\"\\\""
	CLASSPATH=$APP_HOME/gradle/wrapper/gradle-wrapper.jar

[Copilot]

The script currently builds a Java command that includes both -classpath and -jar (with a non-path CLASSPATH). If the intent is to run the wrapper via -jar, drop the -classpath argument and the CLASSPATH variable altogether; otherwise keep the standard -classpath ... org.gradle.wrapper.GradleWrapperMain invocation. Mixing both makes the wrapper harder to reason about and may behave differently across JVMs.

Suggested change

	-jar "$APP_HOME/gradle/wrapper/gradle-wrapper.jar" \
	org.gradle.wrapper.GradleWrapperMain \

CLASSPATH is set to empty but still passed via -classpath when launching the wrapper JAR. If you are using java -jar, the -classpath flag is unnecessary; removing it (and the empty CLASSPATH assignment) avoids potential argument-parsing edge cases on Windows shells.
