Is there some sort of “no newline at eof” rules for bash scripts?

Question

I have two files, an env file and a run file. When I deploy them to my Ubuntu Server box I get the error:

./start-admin: line 10: syntax error: unexpected end of file

If I deploy and then add a newline to the end of the file, it will show the error. If I then remove it the error goes away. If I deploy again and don't add the newline, it still shows the error, but if I then add a newline the error goes away. What could possibly cause that?

Below are my scripts:

env:

if [ "x${WD}" == "x" ];  then echo "missing required conf \"\${WD}\"" >&2; exit -1; fi

export JAVA_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64
export JAR_FILE="$WD/mfa-admin.jar"
export MYSQL_URL=url1
export MYSQL_USER=root
export MYSQL_PASSWORD=pwd
export DB_URL=url2
export DB_USER=user
export DB_PASSWORD=pwd2

export EMAIL_HOST=mail-inbox
export EMAIL_PORT=25
export EMAIL_PERMISSION=false
export FAKE_EMAIL=email
export ACTIVATION_URL=url

export BIND_HOST=0.0.0.0
export BIND_PORT=8282

start:

WD=`dirname $0`;

JAVA_OPTS=""

  . $WD/admin.env.conf

When I have obtained this message, it is the result of mismatched `, ', or " strings within the script. Sometimes this also happens with mismatched if/then/fi, do/while, or case/esac statements.  I'd strongly check out your scripting closely.
