Building CraftBukkit for Minecraft 1.7.10

This tutorial was made due to the sheer amount of errors when compiling 1.7.10-era server software. Now we can finally make clean builds easily again.

Bukkit

We need this since it is a dependency.

Cloning Bukkit

git clone https://github.com/Bukkit/Bukkit.git
cd Bukkit

Fixing the pom.xml

This will remove the outdated & unnecessary repos.

sed -i '25,38d' pom.xml

This will fix the JDK version.

sed -i 's,<source>1.6</source>,<source>1.8</source>,g' pom.xml
sed -i 's,<target>1.6</target>,<target>1.8</target>,g' pom.xml

Installing Bukkit

mvn install

CraftBukkit

Make sure to cd .. after installing Bukkit!

Cloning CraftBukkit

This will clone an unmodified fork used by Paper.

git clone https://github.com/zachbr/CraftBukkit.git
cd CraftBukkit

Fixing the pom.xml

This will remove Overmapped, which deals with mappings. It breaks when compiling.

sed -i '324,341d' pom.xml

This will remove the outdated repos, and add Paper's repo.

sed -i '28,37d;41,44d;48,51d' pom.xml
sed -i 's,</repositories>,<repository><id>papermc</id><url>https://repo.papermc.io/repository/maven-public/</url></repository></repositories>,g' pom.xml

This will fix the JDK version.

sed -i 's,<source>1.6</source>,<source>1.8</source>,g' pom.xml
sed -i 's,<target>1.6</target>,<target>1.8</target>,g' pom.xml

Compiling CraftBukkit

mvn package
