    <p>I wanted to use groovy for a little ftp script and found this post <a href="http://www.hhhhq.org/blog/2009/05/01/ftp-using-groovy-and-ant/" rel="noreferrer">http://www.hhhhq.org/blog/2009/05/01/ftp-using-groovy-and-ant/</a> Since there were several dependencies I wanted to use Grape. All dependencies are resolved and present in the cache. But I can't get Ant to find the optional tasks in the other libs. It always says</p> <pre><code>Caught: : Problem: failed to create task or type ftp Cause: the class org.apache.tools.ant.taskdefs.optional.net.FTP was not found. This looks like one of Ant's optional components. Action: Check that the appropriate optional JAR exists in -ANT_HOME\lib -the IDE Ant configuration dialogs Do not panic, this is a common problem. The commonest cause is a missing JAR. This is not a bug; it is a configuration problem at GrabTest.runMe(GrabTest.groovy:15) at GrabTest.run(GrabTest.groovy:26) </code></pre> <p>Groovy Version: 1.6.5 JVM: 1.6.0_15</p> <p>Here is my source code</p> <pre><code>@Grab(group='ant', module='ant', version='[1.6.5,)') @Grab(group='ant', module='ant-nodeps', version='[1.0,)') @Grab(group='ant', module='ant-apache-oro', version='[1.0,)') @Grab(group='ant', module='ant-commons-net', version='[1.0,)') @Grab(group='apache-oro', module='jakarta-oro', version='[2.0.8,)') @Grab(group='commons-net', module='commons-net', version='[1.4,)') def runMe() { // works println getClass().getClassLoader().loadClass("org.apache.tools.ant.taskdefs.optional.net.FTP") def ant = new AntBuilder() println getClass().getClassLoader() //groovy.lang.GroovyClassLoader$InnerLoader println ant.getClass().getClassLoader() //org.codehaus.groovy.tools.RootLoader ant.ftp( server:"ftp.foo.com", userid:"user", password:"passwd", passive:"yes", verbose:"yes", remotedir:"/pub/incoming", binary:"yes" ) { fileset( dir:"." ) { include( name:"**/*.gz" ) } } } runMe() </code></pre> <p>As you can see I suspect the classloader of being the problem, it seems that Grape doesn't inject the dependencies there. Any idea of how I can get it to work?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
