Setup of maven plugin for using QueryDSL with a MySQL database

I'm trying to setup my project so that I can use querydsl-sql against a MySQL database. I'd like to get the classes and generate the classes using maven and am having problems setting up the plugin.

I've tried configuring the pom.xml from the example available here

<plugin>
    <groupId>com.mysema.querydsl</groupId>
    <artifactId>querydsl-maven-plugin</artifactId>
    <version>2.1.0</version>
    <executions>
        <execution>
            <goals>
                <goal>export</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
    开发者_开发技巧    <jdbcDriver>com.mysql.jdbc.Driver</jdbcDriver>
        <jdbcUrl>jdbc:mysql:mydb:3306/alltrades</jdbcUrl>
        <jdbcUser>mvaz</jdbcUser>
        <packageName>com.three60t.tools.bonus.persistence</packageName>
        <targetFolder>${project.basedir}/target/generated-sources/java</targetFolder>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.6</version>
        </dependency>
    </dependencies>
</plugin>

The dependency to mysql-connector-java is also given in the pom. The problem that I'm getting is that it doesn't seem to find the driver:

Can someone help me with this? How can I specify the driver?

Your dependencies seem to be correct, but your JDBC URL looks funky. Try <jdbcUrl>jdbc:mysql://localhost:3306/alltrades</jdbcUrl>. The MySQL Reference Manual states the following:

The JDBC URL format for MySQL Connector/J is as follows, with items in square brackets ([, ]) being optional:

jdbc:mysql://[host][,failoverhost...][:port]/[database] » [?propertyName1][=propertyValue1][&propertyName2][=propertyValue2]...

If the host name is not specified, it defaults to 127.0.0.1. If the port is not specified, it defaults to 3306, the default port number for MySQL servers.

You also might need to specify a jdbcPassword. For other options look at the Querydsl Reference Manual.

---

The driver is specified correctly, if the driver would be wrong you would get a different Exception :

Class.forName(jdbcDriver); 
Connection conn = DriverManager.getConnection(jdbcUrl, jdbcUser, jdbcPassword);

Does this also fail in isolation? It looks like an error in the jdbcUrl format.
