Converting to EPUB3
The Asciidoctor EPUB3 gem (asciidoctor-epub3) is bundled inside the AsciidoctorJ EPUB3 jar (asciidoctorj-epub3). To use it, simply add the asciidoctorj-epub3 jar to your dependencies. The version of the AsciidoctorJ EPUB3 jar aligns with the version of the Asciidoctor EPUB3 gem.
Here’s how you can add the AsciidoctorJ EPUB3 jar to your Maven dependencies:
<dependencies> <dependency> <groupId>org.asciidoctor</groupId> <artifactId>asciidoctorj-epub3</artifactId> <version>1.5.0-alpha.19</version> <scope>runtime</scope> </dependency> </dependencies>

= Content Title Author Name [abstract] This is the actual content. == First Section And off we go.
And finally we can convert the document to EPUB3 using AsciidoctorJ.
asciidoctor.convertFile(new File("spine.adoc"), options().safe(SafeMode.SAFE).backend("epub3").get()); (1) (2) assertThat(new File("target/test-classes/index.epub").exists(), is(true));
