             Summary: bin/solr script checks for the presence of the JAR command before resolving java (where it might also find jar)
                 Key: SOLR-7641
                 URL: https://issues.apache.org/jira/browse/SOLR-7641
             Project: Solr
          Issue Type: Bug
    Affects Versions: 5.1, 5.0, 5.2
            Reporter: Timothy Potter
             Fix For: 5.3


I have SOLR_JAVA_HOME set to point to a valid JDK in my bin/solr.in.sh

{code}
SOLR_JAVA_HOME="/home/ubuntu/jdk1.8.0_45"
{code}

Note: I do not have JAVA_HOME set in my environment nor is it in my PATH.

And yet, when I run bin/solr, I get the following error:

{code}
$ bin/solr start -cloud -p 8984 -d cloud84 -f
This script requires extracting a WAR file with either the jar or unzip utility, please install these utilities or contact your administrator for assistance.
{code}

I think this code in bin/solr should be after the script resolves the location of "java" so it can check there for "jar" and use that rather than failing the script as it's doing now.
{code}
if hash jar 2>/dev/null ; then      # hash returns true if jar is on the path
  UNPACK_WAR_CMD=("$(command -v jar)" xf)
elif hash unzip 2>/dev/null ; then  # hash returns true if unzip is on the path
  UNPACK_WAR_CMD=("$(command -v unzip)" -q)
else
  echo -e "This script requires extracting a WAR file with either the jar or unzip utility, please install these utilities or contact your administrator for assistance."
  exit 1
fi
{code}
