به این ترتیب دیگر نیازی به تعریف یک url به maven نخواهد بود.

برای دیدن این کتابخانه در صفحه jcenter به ترتیب شناسه‌های Group_ID.Artifact.version را دنبال کنید، یعنی برای ما می‌شود:

com/plus/androidbreadcrumb/1.0

نکته دوم: در صورتی که پکیج خودتان را حذف کنید، چیزی از روی jcenter حذف نمی‌شود. فقط به یاد داشته باشید که برای حذف آن باید ابتدا نسخه‌های مختلف آپلود شده را حذف کنید تا پکیج از جی سنتر هم حذف شود.

1. پکیج شما در jcenter تایید شده باشد.
2. با مخزن شما در sonatype موافقت شده باشد.

در صورتیکه دو مرحله‌ی بالا صورت گرفته باشند، در صفحه‌ی پکیج اختصاصی، بر روی گزینه‌ی mavenCentral کلیک کنید:

پس از آن باید نام کاربری و کلمه‌ی عبورتان را در SonaType، وارد کنید و گزینه‌ی sync را بفشارید:

در صورتیکه پیام موفقیت در سینک را بدهد، پکیج شما منتقل شده‌است. در غیر این صورت خطای آن را اعلام می‌کند و باید برای رفع آن تلاش کنید تا خطاها از بین بروند. برای اینکه بتوانید این پکیج را در لیست mavenCentral ببینید، مثل همان چیزی که در بالاتر گفته شد، شناسه‌ی گریدل را دنبال کنید.
