Jose Maria Arranz shares his experience with the challenges of publishing on Maven Central and how using Bintray, recommended by JFrog employee @jbaruch, provided a simpler alternative. Arranz highlights the difficulties of the Sonatype process and praises Bintray for its user-friendly interface that allows for easy uploading and signing of artifacts using GnuPG keys. This solution enabled him to release his project, RelProxy, on both JCenter and Maven Central with greater ease. He acknowledges that while some steps could be further automated, the current process with Bintray's auto-signing and uploading is sufficient for his needs, especially since releasing occurs infrequently. Arranz also notes that JCenter offers additional benefits, such as being a pre-configured repository in some environments, implying a successful publishing experience overall.
