Unable to embed fonts in PDF

[mraible]

When InfoQ tried to upload the prepress version of the 7.0.0 release to Lulu, it failed because they were unable to embed the fonts in the PDF.

@ggrossetie Maybe this is caused by emojis? I see the following warnings when I run ./gradlew prepress:

asciidoctor-pdf-1.5.3

FYI, Asciidoctor PDF 1.5 is no longer supported. The current release is 2.3.7.

@mojavelinux I need to find out where this version is specified. I don't see it in build.gradle. Any idea how to upgrade?

[ggrossetie]

You can update the version in the asciidoctorj block.

To override set asciidoctorj.pdfVersion or asciidoctorPdf.asciidoctorj.pdfVersion.

You might want to add Noto Emoji to support (black and white) emoji:

@ggrossetie I tried upgrading with this:

asciidoctorj {
    version = '2.5.7'
    pdfVersion = '2.3.7'
    requires file('src/main/ruby/asciidoctor-pdf-extensions.rb')
}

It fails with:

Could not set unknown property 'pdfVersion' for extension 'asciidoctorj' of type org.asciidoctor.gradle.jvm.AsciidoctorJExtension_Decorated.

I also tried the following:

asciidoctorj {
    version = '2.5.7'
    asciidoctorj.pdfVersion = '2.3.7'
    requires file('src/main/ruby/asciidoctor-pdf-extensions.rb')
}

asciidoctorj {
    version = '2.5.7'
    asciidoctorPdf.asciidoctorj.pdfVersion = '2.3.7'
    requires file('src/main/ruby/asciidoctor-pdf-extensions.rb')
}

The last one results in:

Could not set unknown property 'pdfVersion' for extension 'asciidoctorj' of type org.asciidoctor.gradle.jvm.AsciidoctorJExtension_Decorated

[ggrossetie]

Oh we are using version 3. Could you please try:

asciidoctorj {
  modules {
    pdf { 
      version '1.2.3'
    }
}

[mraible]

That seemed to work. Thanks!
