+<div class="sectionbody">
+<div class="paragraph">
+<p>Previous versions of CliBuilder used Apache <a
href="https://commons.apache.org/proper/commons-cli/index.html";>Commons CLI</a>
as the underlying parser library.
+From Groovy 2.5, there is an alternative version of CliBuilder based on the <a
href="https://github.com/remkop/picocli";>picocli</a> parser.</p>
+</div>
+<div class="paragraph">
+<p>It is recommended that applications explicitly import either
<code>groovy.cli.picocli.CliBuilder</code> or
<code>groovy.cli.commons.CliBuilder</code>. The
<code>groovy.util.CliBuilder</code> class is deprecated and delegates to the
Commons CLI version for backwards compatibility.</p>
+</div>
+<div class="paragraph">
+<p>New features will likely only be added to the picocli version, and
<code>groovy.util.CliBuilder</code> may be removed in a future version of
Groovy.
+The Commons CLI version is intended for applications that rely on the
internals of the Commons CLI implementation of CliBuilder and cannot easily
migrate to the picocli version.</p>
+</div>
+<div class="paragraph">
+<p>Next, let’s look at some new features in Groovy 2.5 CliBuilder.</p>

+<p>Options can be boolean flags or they can take one or more option parameters.
+In previous versions of CliBuilder, you would have to specify <code>args:
1</code> for options that need a parameter, or
+<code>args: '+'</code> for options that accept multiple parameters.</p>
+</div>
+<div class="paragraph">
+<p>This version of CliBuilder adds support for typed options. This is
convenient when processing parse results,
+but additionally, the number of arguments is inferred from the type,

standard practice and separate diagnostic output from the program output: If

<p>It’s been a productive time for the Apache Groovy project recently.
We recently released versions 4.0.4, 3.0.12 and 2.5.18 with 42, 21 and 15 fixes
and improvements respectively. Two quick highlights for the 4.0.4 release
before getting into more details about the release.</p>
