3 years ago Started packaging the necessary files inside the project, in a JCEF folder, and implementing code that will copy all of the files to the user.home under the BibleGetPlugin directory. It was working on first test, here's the code:
private static void setNativeLibraryDir() throws NoSuchFieldException, IllegalArgumentException, IllegalAccessException, IOException {
String nativelibrarypath = "";
if(SystemUtils.IS_OS_WINDOWS){
nativelibrarypath = "/AppData/Roaming/BibleGetOpenOfficePlugin/JCEF";
}
else if(SystemUtils.IS_OS_MAC_OSX){
nativelibrarypath = "/Library/Application Support/BibleGetOpenOfficePlugin/JCEF";
}
else if(SystemUtils.IS_OS_LINUX){
nativelibrarypath = "/.BibleGetOpenOfficePlugin/JCEF";
}
nativelibrarypath = System.getProperty("user.home") + nativelibrarypath;
//first let's check if the JCEF directory exists in the user's home under our BibleGetOpenOfficePlugin directory
//and if not, we create it
Path JCEFpath = Paths.get(nativelibrarypath);
Path JCEFlocalespath = Paths.get(nativelibrarypath, "locales");
Path JCEFswshaderpath = Paths.get(nativelibrarypath, "swiftshader");
if(Files.notExists(JCEFpath)){
File jcefDirectory = new File(nativelibrarypath);
jcefDirectory.mkdirs();
}
if(Files.notExists(JCEFlocalespath) ){
File jcefLocalesDir = new File(nativelibrarypath, "locales");
jcefLocalesDir.mkdir();
}
if(Files.notExists(JCEFswshaderpath) ){
File jcefSwShaderDir = new File(nativelibrarypath, "swiftshader");
jcefSwShaderDir.mkdir();
}
String[] JCEFfiles = new String[]{

if(JAVAVERSION == 8){
final Field usrPathsField = ClassLoader.class.getDeclaredField("usr_paths");

}
}However when trying to push to github, I got an error because libcef.dll is slightly over 100MB which is the limit for github without resorting to git lfs. This would just make development that much more complicated.
So I'm thinking of trying another route: downloading the zip directly from the jcefbuild github releases on program initialization, and unzipping the package to the user.home under the BibleGetPluginOpenOffice directory.
Now that the functionality for JCEF is created and tested and pretty much complete, we have to move to the next phase of figuring out how to package and distribute the JCEF native libraries and make them available to the java.library.path.
