 \subsection{Creating Maven Package}
+% Gradle
+% Testing
+% GitHub CI
+\begin{itemize}
+  \item XPC package is not published on a public Maven repository
+  \item There has been a pull request that was merged to the \textit{develop} branch
+    that provides Maven POMs~\cite{xpc:pom}. However, the maintainer for the
+    project, at the time, did not have enough time to figure out the process of
+    publishing the package to a Maven repository~\cite{xpc:pom-time}
+  \item Therefore, had to find an alternative way to implement
+  \item Jitpack~\cite{jitpack}
+  \begin{itemize}
+    \item In theory, simple to publish a repository, all that is required is a GitHub
+      repository and searching if one has already been created on JitPack or build and publish
+      a specific version
+    \item However, due to the structure of the XPC repository, JitPack could not locate the
+      build tools (Apache Maven in this case) as JitPack only searches on the root directory
+      for the compatible build tools
+  \end{itemize}
+  \item Gradle gitRepository~\cite{gradle:gitRepository}
+  \begin{itemize}
+    \item There was not a lot of documentation
+    \item Ambiguous on how to define directory for where the Java library is located in the Git repository
+    \item However, as XPC was only built with Maven, Gradle was not able add the dependency as \verb|gitRepository()|
+      only works with Gradle builds~\cite{gradle:gitRepoGradleOnly}
+  \end{itemize}
+\item Resorted to using a compiled Jar file and adding the dependency to Gradle
+\item Not happy about that because it means maintaining it will be more difficult as
+  it is not as simple as just changing the version number
+\item Later, resorted to adding Gradle build files to XPC
+\item Used automatic conversion from Maven to Gradle using \verb|gradle init| command~\cite{gradle:migratePOM}
+\item Had to add local dependencies due to how Gradle works differently
+\item Had to fix previous structure of Maven POM as the grouping as not good
+\end{itemize}
