javax.xml.parsers

The package javax.xml.parsers matches JAXP and can be found in jaxp-api-1.4.5.jar. For Gradle, you’d use this:

compile group: 'javax.xml.parsers', name: 'jaxp-api', version: '1.4.5'

It is also distributed in the standard library. In Java 9 it is in module java.xml.

javax.xml.soap

The package javax.xml.soap corresponds to SAAJ and can be found in saaj-api-1.3.5.jar. For Gradle, you’d use this:

compile group: 'javax.xml.soap', name: 'saaj-api', version: '1.3.5'

It is also distributed in the standard library. In Java 9 it is in module java.xml.ws, but how this module is marked with @Deprecated(since="9", forRemoval=true), then it is better to import it as a library in Gradle than to use the standard Java 9 module. This does not mean that SAAJ has been discontinued or abandoned, it just means that it will no longer be distributed as part of the JDK after Java 9, should then be added as an external dependency (exactly what Gradle does).

java.net, java.io and java.util

The packages java.net, java.io and java.util are in the standard library. In Java 9, all of them are in the module java.base. So you don’t have to do anything special at Gradle to use them.

org.w3c.dom and org.xml.sax

The packages org.w3c.dom and org.xml.sax are also in the standard library. In Java 9, they are in the module java.xml.
