Java – httpclient publishing progress and multipartentitybuilder

I tried using httpclient 4.3 3 and multipartytybuilder achieve progress when uploading files

So I actually execute a post request with the following code

HttpClientBuilder builder = HttpClientBuilder.create();
HttpClient httpClient = builder.build();

HttpPost httpPost = new HttpPost(uploadUrl);

multipartentityBuilder entityBuilder = multipartentityBuilder.create();
entityBuilder.addPart("filea",new FileBody(filea));
entityBuilder.addPart("fileb",new FileBody(fileb));

final httpentity entity = entityBuilder.build();
httpPost.setEntity(entity);

HttpResponse response = httpClient.execute(httpPost);

Do you know how to get real progress from uploading? I searched a lot - but these examples are for Android, not simple Java or old versions of httpclient, and they don't work for me

Solution

I just found a solution:

You need an httpentitywrapper to calculate the bytes processed and call back

ProgresshttpentityWrapper.ProgressCallback progressCallback = new ProgresshttpentityWrapper.ProgressCallback() {

        @Override
        public void progress(float progress) {
            //Use the progress
        }

    }

httpPost.setEntity(new ProgresshttpentityWrapper(entityBuilder.build(),progressCallback));

This is progresshttpentitywrapper: https://github.com/x2on/gradle-hockeyapp-plugin/blob/master/src/main/groovy/de/felixschulze/gradle/util/ProgressHttpEntityWrapper.groovy Complete code for
