Bashスクリプトに「eofへの改行禁止」ルールがありますか？

envファイルと実行可能ファイルという2つのファイルがあります。 Ubuntuサーバーに展開するとエラーが発生します。

./start-admin: 行 10: 構文エラー: 予期しないファイルの終わり

展開してファイルの末尾に改行を追加すると、エラーが表示されます。削除するとエラーが消えます。再デプロイして改行を追加しないとエラーが表示されますが、改行を追加するとエラーは消えます。この問題の原因は何ですか？

以下は私のスクリプトです。

環境：

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

スタート：

WD=`dirname $0`;
