通過Ruby連接到HSQL並關閉服務器

我想寫一個Ruby腳本來殺死我的本地主機上的數據庫服務器。通過Ruby連接到HSQL並關閉服務器

當我運行'ant hsql'它啓動數據庫（輸出如下），我必須保持該終端窗口打開。構建文件：/Users/cparaiso/dev/src/testproject-src/build.xml

hsql: 

install-parent-pom: 
[artifact:install] [INFO] Installing /Users/cparaiso/dev/src/testproject-src/pom.xml to /Users/cparaiso/.m2/repository/org/jasig/portal/uportal-parent/4.0.3/uportal-parent-4.0.3.pom

    [java] [[email protected]]: To close normally, connect and execute SHUTDOWN SQL 
    [java] [[email protected]]: From command line, use [Ctrl]+[C] to abort abruptly

我的問題是我怎麼能不關閉在Ruby中使用kill命令殺掉該進程的服務器？

如果我試圖通過kill命令殺死進程，我會得到'BUILD FAILED'並且它會卡住，直到我按下Ctrl + C鍵。這不是我想要的。有任何想法嗎？ TIA

我不知道如何在Ruby中發出SQL語句，但是如果連接到數據庫服務器併發出SQL語句SHUTDOWN，它將關閉服務器進程。
