<h1 id="Why_is_my_required_bundle_with_version_x.y.z._not_resolved.3F">Why is my required bundle with version x.y.z. not resolved?</h1>
<p>To specify a version in a Require-Bundle header an (OSGi standard) attribute
<b>bundle-version</b> is needed.
</p>
<p>&lt;code&gt;
Require-Bundle: bar;bundle-version="
<a href="x.y.z,x.y.z">x.y.z,x.y.z</a>"
&lt;/code&gt;
</p>
<p>The attribute is spelled
<b>bundle-version=</b> rather than
<b>version=</b> as used with Import-Package. A misspelled attribute can show the following error:
</p>
<p>&lt;code&gt;</p>
<pre> Resolver report:
A Require-Bundle could not be resolved. Caused by missing constraint in bundle &lt;foo_1.0.0&gt;
constraint: &lt;Require-Bundle: bar; bundle-version="0.0.0"&gt;
</pre>
<p>&lt;/code&gt;</p>
<p>If a required bundle cannot be resolved check the spelling of the attribute as well as the location of the required bundle.</p><hr/>
