I already solved it, I did it like that.

 

in class JiraUtil.java .-

public boolean addAttachmentToIssue(String issueKey, String fullfilename) throws IOException {

CloseableHttpClient httpclient = HttpClients.createDefault();

HttpPost httppost = new HttpPost(JIRA_URL + "rest/api/2/issue/" + issueKey + "/attachments");
httppost.setHeader("X-Atlassian-Token", "nocheck");
httppost.setHeader("Authorization", "Basic " + new String(Base64.encode((JIRA_ADMIN_USERNAME + ":" + JIRA_ADMIN_PASSWORD).getBytes())));

File fileToUpload = new File(fullfilename);
FileBody fileBody = new FileBody(fileToUpload);

MultipartEntityBuilder builder = MultipartEntityBuilder.create();

HttpEntity entity = builder.addPart("file", fileBody).build();

httppost.setEntity(entity);
String mess = "Executing request: " + httppost.getRequestLine();
System.out.println(mess);
//logger.info(mess);
CloseableHttpResponse response;

try {
response = httpclient.execute(httppost);
} finally {
httpclient.close();
}

if (response.getStatusLine().getStatusCode() == 200) {
return true;
} else {
return false;
}
}

public boolean getAttachmentFromIssue(String contentURI, String fullfilename) throws IOException {

CloseableHttpClient httpclient = HttpClients.createDefault();

try {
HttpGet httpget = new HttpGet(contentURI);
httpget.setHeader("Authorization", "Basic " + new String(Base64.encode((JIRA_ADMIN_USERNAME + ":" + JIRA_ADMIN_PASSWORD).getBytes())));

System.out.println("Executing request: " + httpget.getURI());

CloseableHttpResponse response = httpclient.execute(httpget);

int status = response.getStatusLine().getStatusCode();

try {
HttpEntity entity = response.getEntity();
if (entity.isStreaming()) {
byte data[] = EntityUtils.toByteArray(entity);
FileOutputStream fout = new FileOutputStream(new File(fullfilename));
fout.write(data);
fout.close();
}
} catch (Exception e) {
System.out.println("error: " + e);
}
} finally {
httpclient.close();
}

return true;
}

 

to use it.-

JsonArray arrayArchivosAdjuntos = jsObj.getAsJsonObject().get("fields").getAsJsonObject().get("attachment").getAsJsonArray();

String otPlKey = jsObj.get("key").getAsString();

for (int i = 0; i < arrayArchivosAdjuntos.size(); i++) {
JsonObject jsArchivo = arrayArchivosAdjuntos.get(i).getAsJsonObject();

if (jiraUtil.getAttachmentFromIssue(jsArchivo.get("content").getAsString(), jsArchivo.get("filename").getAsString())) {
System.out.println("Can download file " + jsArchivo.get("filename").getAsString() + " of the " + otPlKey);
} else {
System.out.println("Can't download file" + jsArchivo.get("filename").getAsString());
}

if (jiraUtil.addAttachmentToIssue(otPrKey, jsArchivo.get("filename").getAsString())) {
System.out.println("Can upload file " + jsArchivo.get("filename").getAsString() + " in " + otPrKey);
} else {
System.out.println("Can't upload file + jsArchivo.get("filename").getAsString());
}

}
