我试图用javafxports编写一个简单的sqlite代码。

build.gradle：

    buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.6'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
    maven {
        url "https://oss.sonatype.org/content/repositories/snapshots/"
    }
    maven {
        url "https://oss.sonatype.org/content/repositories/releases"
    }

}

ext.CHARM_DOWN_VERSION = "1.0.0"

dependencies{
    compile 'org.xerial:sqlite-jdbc:3.8.11'

    compile "com.gluonhq:charm-down-common:$CHARM_DOWN_VERSION"
    desktopRuntime "com.gluonhq:charm-down-desktop:$CHARM_DOWN_VERSION"
    androidRuntime "com.gluonhq:charm-down-android:$CHARM_DOWN_VERSION"
    iosRuntime "com.gluonhq:charm-down-ios:$CHARM_DOWN_VERSION"
}
mainClassName = 'com.gluonapplication.version16'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
    }
    ios {
        infoPList = file('src/ios/Default-Info.plist')
        forceLinkClasses= ['com.gluonhq.**.*', 'org.sqlite.**.*']
    }
}

我的JavaCode：

public static Label msg = new Label();

@Override
public void start(Stage stage) {
    StackPane root = new StackPane();

    root.getChildren().add(msg);
    Rectangle2D visualBounds = Screen.getPrimary().getVisualBounds();
    Scene scene = new Scene(root, visualBounds.getWidth(), visualBounds.getHeight());

    stage.getIcons().add(new Image(version16.class.getResourceAsStream("/icon.png")));
    stage.setScene(scene);
    stage.show();

    try {
        testSqli();
    } catch (SQLException e) {
        e.printStackTrace();
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
}
public static void testSqli() throws SQLException, ClassNotFoundException {
    String driver = "org.sqlite.JDBC";
    //Class.forName("SQLite.JDBCDriver");
    Class.forName(driver);
    String dbName = "mtt8.db";
    String dbUrl = "jdbc:sqlite:" + dbName;

    //create table
    Statement st = null;
    Connection conn = DriverManager.getConnection(dbUrl);
    st = conn.createStatement();
    st.executeUpdate("DROP TABLE IF EXISTS village;");
    st.executeUpdate("CREATE table village (id int, name varchar(20))");
    //insert row?
    st.executeUpdate("INSERT INTO village VALUES (111, 'Concretepage')");

    //select?
    String query = "SELECT id, name from village";
    ResultSet rs = null;
    rs = st.executeQuery(query);

    while (rs.next()) {
        int id = 0;
        id = rs.getInt(1);
        String name = null;
        name = rs.getString(2);
        msg.setText("id:" + id + ", name: " + name);
        System.out.println("id:" + id + ", name: " + name);
        st.executeUpdate("DELETE from village");
        rs.close();
    }
}

我用./gradlew launchIOSDevice发送它并得到以下错误：

有人可以帮我吗，如何在代码中提供权限，以便创建sqlite数据库？

谢谢
