ant Task SQL wirft „keine ResultSet verfügbar“ mit org.sqlite.JDBC Treiber

Question

Ich versuche org.sqlite.JDBC zu verwenden, um eine SQLite-Datenbank in ant zu erstellen und zu aktualisieren. Die sqlitejdbc-v056.jar kommt von http://www.zentus.com/sqlitejdbc/ und ist die neueste Version (056)

Das ist mein build.xml:

<?xml version="1.0" encoding="utf-8"?>

<project name="My Project" default="mytarget" basedir=".">

    <path id="antclasspath">
        <fileset dir="_ant">
            <include name="*.jar"/>
        </fileset>
    </path>

    <target name="mytarget">
        <property name="antclasspathar" refid="antclasspath" />
        <echo message="Classpath is ${antclasspathar}"/>
        <sql
            driver="org.sqlite.JDBC"
            url="jdbc:sqlite:C:/Projects/dummy/test.db"
            userid=""
            password=""
            classpathref="antclasspath"
        >
            DROP TABLE IF EXISTS people;
            CREATE TABLE people (name, occupation);
        </sql>

    </target>

</project>

Dies ist die Ausgabe erhalte ich:

Answer 1

DDL (Data Definition Language, zum Beispiel CREATE, DROP, etc.) Aussagen hat nicht gibt ein ResultSet während Ant-Skript scheinbar es erwartet wird. Zumindest wird die SQLException erzählt im Grunde, dass Sie. Ich mache Ant nicht extensiv, also kann ich nicht im Detail gehen, aber Sie müssen zumindest das Skript ändern, so, so dass nicht Rückgabewert erwartet wird.
