If optional is set to true, the dependency is considered optional; if set to false, the dependency is required.<\/p>\n<p>For example, here is a sample using optional dependencies:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">dependencies<\/span>&gt;<\/span>\r\n  <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">dependency<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">groupId<\/span>&gt;<\/span>org.example<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">groupId<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">artifactId<\/span>&gt;<\/span>example-library<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">artifactId<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">version<\/span>&gt;<\/span>1.0.0<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">version<\/span>&gt;<\/span>\r\n    <span class=\"hljs-tag\">&lt;<span class=\"hljs-name\">optional<\/span>&gt;<\/span>true<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">optional<\/span>&gt;<\/span>\r\n  <span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">dependency<\/span>&gt;<\/span>\r\n<span class=\"hljs-tag\">&lt;\/<span class=\"hljs-name\">dependencies<\/span>&gt;<\/span>\r\n<\/code><\/pre>\n<p>In this example, the dependency on example-library is marked as optional. If example-library cannot be found during the project build process, Maven will ignore the inclusion of this dependency and continue with the build.<\/p>\n<p>It&#8217;s important to note that the use of optional dependencies should be approached with caution and only used when necessary. This is because optional dependencies may complicate the project&#8217;s dependency structure and introduce unstable or incompatible libraries.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In Maven, you can use the optional attribute to specify if a dependency is considered optional.
