    <p>There are very few documentations and examples on this (those exists are useless).</p> <p>I would like to copy all the dependencies of a given pom.xml file. Usually, I can use <code>mvn dependency:copy-dependencies</code> on command line or use <code>maven-dependecy-plugin</code> configuration in the pom file.</p> <p>However, I would like to do it programmatically on a given pom.xml file. So far, I figured that I will need to use <code>MavenCli</code></p> <pre><code>MavenCli cli = new MavenCli(); cli.doMain(new String[]{"clean", "dependency:copy-dependencies", "-DincludeScope=runtime"}, "C:\\workspace\\gui", null, null); </code></pre> <p>where <code>"C:\\workspace\\gui"</code> is a directory containing a pom.xml</p> <p>but the above code gives me the following error:</p> <pre><code> [ERROR] Failed to execute goal on project test-pom: Could not resolve dependencies for project gigadot:test-pom:jar:0.5-SNAPSHOT: Failed to collect dependencies for [commons-lang:commons-lang:jar:2.6 (compile), commons-io:commons-io:jar:2.0.1 (compile), org.apache.commons:commons-exec:jar:1.1 (compile), org.apache.commons:commons-math:jar:2.2 (compile), xom:xom:jar:1.2.5 (compile), log4j:log4j:jar:1.2.16 (provided)]: Failed to read artifact descriptor for org.apache.commons:commons-math:jar:2.2: Could not transfer artifact org.apache.commons:commons-math:pom:2.2 from/to central (http://repo1.maven.org/maven2): No connector available to access repository central (http://repo1.maven.org/maven2) of type default using the available factories -&gt; [Help 1] </code></pre> <p>Does anyone know how to solve this problem?</p>

    2. COGiven that the pom is just an xml file, you could just use a dom library (like dom4j) and an xpath expression to grab all dependencies - just out of interest, why do you need to do this?

    3. CO@Romski doing what you said will not include the transitive dependencies. The reason I wanted to do this is because I was building dynamic plugable system. I would like the dependencies of the jar plugin to be included in the classpath automatically.

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.
