Michael Osipov commented on MWRAPPER-90:
----------------------------------------
POSIX shell provides only one array -- that is {{$@}}.
> Use arrays to preserve potential whitespace in arguments
> --------------------------------------------------------

> Key: MWRAPPER-90
> URL: https://issues.apache.org/jira/browse/MWRAPPER-90
> Project: Maven Wrapper
> Issue Type: Improvement
> Components: Maven Wrapper Scripts
> Reporter: Benjamin Marwell
> Priority: Major
>
> The bash scripts call mvn using:
> {code:java}
> # shellcheck disable=SC2086 # safe args
> exec "$JAVACMD" \
> $MAVEN_OPTS \
> $MAVEN_DEBUG_OPTS \
> -classpath "$MAVEN_PROJECTBASEDIR/.mvn/wrapper/maven-wrapper.jar" \
> "-Dmaven.multiModuleProjectDirectory=${MAVEN_PROJECTBASEDIR}" \
> ${WRAPPER_LAUNCHER} $MAVEN_CONFIG "$@"{code}
> However, this might mangle parameters containing spaces into multiple
> parameters. It would be only safe when using arrays and use quotes, e.g.
> {{{}"${MAVEN_OPTS[@]}"{}}}. Same for the others. This would also allow us to
> disable the shellcheck check.
