Hi all!

I'm trying to upload a pdf file to one of my Jira issues using Java. I tried older solutions posted on this forum, but they doesn't seem to work. Here is what I have now:

public CloseableHttpResponse addAttachment(String baseUrl, String issueKey, String filePath) throws IOException{
try (CloseableHttpClient client = HttpClientBuilder.create().build();) {
HttpPost httpPost = new HttpPost(baseUrl+"/"+issueKey+"/attachments");
httpPost.setHeader(new BasicHeader("Authorization", "Bearer " + apiKey));
httpPost.setHeader("X-Atlassian-Token", "no-check");
httpPost.setHeader("Content-Type", "multipart/form-data;boundary=gc0p4Jq0M2Yt08jU534c0p");

File file = new File(filePath);
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addBinaryBody("file", file, ContentType.APPLICATION_OCTET_STREAM, file.getName());

HttpEntity entity = builder.build();


CloseableHttpResponse response = client.execute(httpPost);

return response;

My problem is that it sends the request and responds with 200, but with a body of: [], and nothing is uploaded. Everything works fine with Postman, so it must be something with my code.

Someone please help me fix it.
