saxon.FeatureKeys importing error in java spring-boot project

I am getting the saxon-importing error like,

The "import net.sf.saxon.FeatureKeys" cannot be resolved. 

How can I add the dependency to resolve the "net.sf.saxon.FeatureKeys" error.

I have already added the given dependency:

<!-- https://mvnrepository.com/artifact/net.sf.saxon/Saxon-HE -->
<dependency>
<groupId>net.sf.saxon</groupId>
<artifactId>Saxon-HE</artifactId>
<version>10.6</version>
</dependency>

Please help me out to resolve this issue.

>Solution :

I think you want import net.sf.saxon.lib.FeatureKeys, see https://www.saxonica.com/html/documentation10/javadoc/net/sf/saxon/lib/FeatureKeys.html
