 ```
 
 ### Compilation
-To compile, the relevant Spigot jars must be installed in the local repository.
+OpenInv now builds with Gradle 8.14.3 using Paperweight userdev for Purpur `1.19.4` on Java 17 / GraalVM 17.
-As OpenInv is compiled against Mojang's mappings, you must run BuildTools with the `--remapped` argument:  
-`java -jar BuildTools.jar --remapped --rev $serverVersion`  
-`$serverVersion` is the version of the server, i.e. `1.18.1`
 
-To compile for a single version, specify the module you are targeting:  
+Build the plugin with:
-`mvn -pl $moduleName -am clean install`  
+`./gradlew build`
-`$moduleName` is the name of the module, i.e. `internal/v1_18_R1`.
 
-To compile for a set of versions, use a profile. Select a profile using the `-P` argument:  
+The server-ready shaded jar is written to:
-`mvn clean package -am -P all`  
+`build/libs/OpenInv-${version}.jar`
-The only provided profile is `all`. The final file is `target/OpenInv.jar`  
-For more information, check out the [official Maven guide](http://maven.apache.org/guides/introduction/introduction-to-profiles.html).

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
