Could not find 'java' executable

使用sonar-scanner执行代码扫描时，提示Could not find 'java' executable in JAVA_HOME or PATH。但是服务器已经配置过了JAVA_HOME。
sonar-scanner使用的是自带的jre，进入/opt/sonar-scanner-4.6.2.2472-linux/bin目录，执行vi sonar-scanner查看。

use_embedded_jre=true
if [ "$use_embedded_jre" = true ]; then
  export JAVA_HOME="$sonar_scanner_home/jre"
fi

if [ -n "$JAVA_HOME" ]
then
  java_cmd="$JAVA_HOME/bin/java"
else
  java_cmd="`which java`"
fi

if [ -z "$java_cmd" -o ! -x "$java_cmd" ] ; then
  echo "Could not find 'java' executable in JAVA_HOME or PATH."
  exit 1
fi

因为我是从其他服务器拷贝过来的，经排查是权限不对，需要进行授权:

[root@localhost ~]# cd /opt/sonar-scanner-4.6.2.2472-linux/bin/
[root@localhost bin]# ./sonar-scanner -v
Could not find 'java' executable in JAVA_HOME or PATH.
[root@localhost bin]# cd ../jre/bin/
