Grails uses flying saucer to generate a PDF file

> To export PDF in Java Web/grails, the best solution on the Internet is to use the [flyingsaucer] (https://github.com/flyingsaucerproject/flyingsaucer "flying saucer") Library.
> There are always various problems that can be found on the Internet with the ready-made V8 jar packages, such as bugs in CSS that 'word-wrapp' does not work,
> We need to download all the source code from the GIT homepage of the project and compile it with ** Maven.

Compile source code
===
Copy the 'pdf 'folder in the 'Flying-saucer-PDF' project source code directory to the source code directory of 'flying-saucer-core;

Modify the 'pom. xml' file of the 'Flying-saucer-PDF 'project and add the 'com. lowagie. itext' package to the compilation dependency:

XML:

4.0.0 Org.xhtml Renderer Flying-saucer-parent 9.0.2-Snapshot Flying-saucer-core Flying saucer is a CSS 2.1 Renderer written in Java. This artifact contains the core rendering and layout code as well as java2d output. Com. lowagie Itext 2.1.7 Jar Flying saucer core Renderer

In the 'Flying-saucer-PDF 'project directory, Maven Compilation: 'mvn Package' will generate a jar package containing the PDF rendering class.
