Michael Osipov reopened MNG-5829:
---------------------------------
Assignee: Michael Osipov
The shell on Solaris is not POSIX-compliant, therefore it does not support the
{{$()}} construct, though this is highly preferred over backticks.
> mvn shell script fails with syntax error on Solaris 10
> ------------------------------------------------------

> Key: MNG-5829
> URL: https://issues.apache.org/jira/browse/MNG-5829
> Project: Maven
> Issue Type: Bug
> Components: Command Line
> Affects Versions: 3.3.3
> Environment: Solaris 10
> Reporter: Zac Thompson
> Assignee: Michael Osipov
> Priority: Minor
>
> The {{$(cmd)}} idiom is used extensively in bin/mvn from lines 199-220, but
> this is not supported by older incarnations of /bin/sh (used on the shebang
> line). The {{`cmd`}} idiom is slightly more portable, and looks like it can
> probably be directly substituted.
> {noformat}
> find_maven_basedir() {
> local basedir=$(pwd)
> local wdir=$(pwd)
> while [ "$wdir" != '/' ] ; do
> wdir=$(cd "$wdir/.."; pwd)
> if [ -d "$wdir"/.mvn ] ; then
> basedir=$wdir
> break
> fi
> done
> echo "${basedir}"
> }
> # concatenates all lines of a file
> concat_lines() {
> if [ -f "$1" ]; then
> echo "$(tr -s '\n' ' ' < "$1")"
> fi
> }
> export MAVEN_PROJECTBASEDIR=${MAVEN_BASEDIR:-$(find_maven_basedir)}
> MAVEN_OPTS="$(concat_lines "$MAVEN_PROJECTBASEDIR/.mvn/jvm.config")
> $MAVEN_OPTS"
> {noformat}
> See MNG-5658 for an earlier case of a similar problem.
