Shell scripts to automatically set up old versions of MCP and FML
Scripts:
- setupFML1.2.5.sh: downloads and sets up a FML 1.2.5 environment.
Requirements: curl, unzip, dos2unix if not on Windows.
Python 2 and Java are required for MCP setup (JDK 6 recommended, JDK 7 works as well).
On macOS, setting the version of Java used is generally very simple:
export JAVA_HOME=/path/to/java/homeOn Linux, setting the version of Java used has a few more steps. Suppose your JDK tarball (Azul or Oracle) was extracted to ~/zulu-jdk-7.56.0.11. Then, in order to set all references in the current terminal session to said JDK version, you must update your PATH. That can be done in the following manner:
export JAVA_HOME="~/zulu-jdk-7.56.0.11"
export PATH="$JAVA_HOME/bin:$PATH" # take note of the '/bin'Note that your original PATH will remain unaffected in any other terminal window. Another alternative would be to source a shell script with the above, as to simplify the process in case you need to use many terminal sessions. If you wish to set your system-wide Java version to this, add the above lines to the end of your ~/.profile and reboot. Uncomment or remove these rows to revert to how it was. update-alternatives to javac may also be used in Debian-based systems.
On Windows, there's a few complications. Old MCP versions will check the registry key Software\JavaSoft\Java Development Kit for the value of CurrentVersion, and will use the JDK found under Software\JavaSoft\Java Development Kit\(value of CurrentVersion) if it exists. You may have to edit the registry to change this. If there's nothing in the registry, it will then use the version of java from javac in PATH, and searches various Program Files locations otherwise.
Here's a table of older JDK download locations:
| Java version | macOS | Windows | Linux |
|---|---|---|---|
| 1.6, OpenJDK | SoyLatte | Azul Zulu | Azul Zulu |
| 1.6, Oracle JDK | Apple Legacy JDK (32 bit) | Oracle Java 6 Archive | Oracle Java 6 Archive |
| 1.7, OpenJDK | Azul Zulu | Azul Zulu | Azul Zulu |
| 1.7, Oracle JDK | Oracle Java 7 Archive | Oracle Java 7 Archive | Oracle Java 7 Archive |
Note for macOS users: it's generally easier to use Java 7 instead of Java 6 on macOS. The Apple Legacy JDK contains 32 bit components, and may not work on macOS 10.15+. I haven't managed to get SoyLatte working, but it's theoretically possible to use it.
Older versions of MCP and Forge take many steps to set up, and sometimes require fixes due to their age. I wrote a guide on how to install Forge 1.2.5 manually some years ago, which was fairly tedious. Using a shell script is hopefully easier than patching files manually.
