Hi, I am following this tutorial

In my pom.xml, add the dependency:

<dependency>
      <groupId>org.nuxeo.runtime</groupId>
      <artifactId>nuxeo-runtime-datasource</artifactId>
      <scope>test</scope>
    </dependency>
In some circumstances, if your test dependencies aren't followed correctly, you may have to add as well:

<dependency>
      <groupId>commons-dbcp</groupId>
      <artifactId>commons-dbcp</artifactId>
      <scope>test</scope>
    </dependency>

My contrib:

<?xml version="1.0"?>
<component name="com.example.datasource.tests">
  <extension target="org.nuxeo.runtime.datasource" point="datasources">
    <datasource name="jdbc/foo" driverClassName="org.h2.Driver"
      maxActive="20" maxIdle="5">
      <property name="url">jdbc:h2:${ds.test.home}/db</property>
    </datasource>
  </extension>
</component>

Junit4 config test:

@Features(CoreFeature.class)
@Deploy("org.nuxeo.runtime.datasource")
@LocalDeploy("myplugin:OSGI-INF/datasource-contrib.xml")
public class MyDataSourceFeature extends SimpleFeature {

    private static final String DIRECTORY = "target/test/h2";
    private static final String PROP_NAME = "ds.test.home";

    @Override
    public void initialize(FeaturesRunner runner) throws Exception {
        File dir = new File(DIRECTORY);
        FileUtils.deleteTree(dir);
        dir.mkdirs();
        Framework.getProperties().put(PROP_NAME, dir.getPath());
        super.initialize(runner);
    }
}

myplugin I got from MANIFEST.MF file

Bundle-SymbolicName: myplugin

My test

@Test
    public void test() throws Exception {
        // look up jdbc/foo
        DataSource ds = DataSourceHelper.getDataSource("foo");
        Connection conn = ds.getConnection();
        try {
            ... use the connection ...
        } finally {
            conn.close();
        }
    }

but I am having this error when run test
