Maven + Dreambot = Jar with dependencies

[yeeter01 392]

Saw some people having issues with Dreambot and libs.   Thought I would yeet this in the snippets real quick to save someone else the trouble of writing their own.  This is a premade pom file for Maven.  If you are unfamiliar with Maven it is a build automation tool created by Apache.   It is great for managing dependencies for building self contained private scripts so no more lib/dependency fuckery.

For starters in the properties change the dreambot.path to wherever your DreamBot folder is located.  On Windows this is C:/Users/yeeter01/Dreambot
 

<properties>
	<dreambot.path>C:/Users/yeeter01/DreamBot</dreambot.path>
</properties>

To add dependencies its as simple as going out to a maven repository like https://mvnrepository.com/ and finding the dependencies you want to use.   I will use google protobuf and simple json for this example

 

<dependencies>
		<dependency>
			<groupId>com.google.protobuf</groupId>
			<artifactId>protobuf-java</artifactId>
			<version>3.11.0</version>
		</dependency>

		<dependency>
			<groupId>com.google.protobuf</groupId>
			<artifactId>protobuf-java-util</artifactId>
			<version>3.11.0</version>
		</dependency>

		<dependency>
			<groupId>com.googlecode.json-simple</groupId>
			<artifactId>json-simple</artifactId>
			<version>1.1.1</version>
		</dependency>

		<dependency>
			<groupId>dreambot</groupId>
			<artifactId>client</artifactId>
			<version>1.0.0</version>
			<scope>system</scope>
			<systemPath>${dreambot.path}/BotData/client.jar</systemPath>
		</dependency>
	</dependencies>

 

Now for the part that was a pain in my ass initially.. the build.  We will use the maven-shade plugin in order to create a shaded jar.  This is just a fancy uber jar.

Jar packaging information -> https://dzone.com/articles/the-skinny-on-fat-thin-hollow-and-uber
Apache Shade plugin information -> https://maven.apache.org/plugins/maven-shade-plugin/

 

	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-shade-plugin</artifactId>
				<version>3.2.1</version>
				<configuration>
					<shadedArtifactAttached>true</shadedArtifactAttached>
					<shadedClassifierName>dep-included</shadedClassifierName>
					<outputDirectory>${dreambot.path}/Scripts</outputDirectory>
				</configuration>
				<executions>
					<execution>
						<phase>package</phase>
						<goals>
							<goal>shade</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>

 

Smash that maven build button and BOOM!  Out comes 2 jar files. 'original-yeetware-0.0.1-SNAPSHOT' and 'yeetware-0.0.1-SNAPSHOT'.  The file with the original prefix is the normal jar generated by maven.  The other will be your shaded jar which can be thrown into the scripts folder ready to rock.   You  can get really fancy with this and auto output the script into there, delete the original, upload to a fileserver etc but this was just a barebones example.

*Disclaimer*
I am no maven expert so probably better ways to do it.

Thanks for sharing. Pretty sweet, and I like that you can rename dependencies internally.
