Installation
JabRef can be either installed (the preferred way) or be used as a portable application.
To get the latest version, head to downloads.jabref.org, download the installer for your system (e.g., dmg files for MacOS and msi files for Windows), run them and follow the on-screen instructions.
Alternatively, on Windows, you can use the chocolatey package manager and execute choco install jabref to get the latest version. On Ubuntu, you can use snap install jabref to get the latest stable version from snapcraft.
The portable version of JabRef is designed to be run from a USB stick (or similar) with no installation.
Download it from downloads.jabref.org. These are generic archive files (e.g., tar.gz files for Linux and MacOS, and zip files for Windows) which need to be extracted. Inside the archive files you will find a bin subdirectory which contains the binary needed to run JabRef (i.e., JabRefMain for Linux and MacOS, and JabRefMain.bat for Windows).
Be sure to activate "Load and Save preferences from/to jabref.xml on start-up (memory stick mode)" in Options → Preferences → General.
In case, you want to take advantage of the latest features, you can use pre-built binaries crafted from the latest development branch. To use the prebuilt binaries, visit builds.jabref.org/master and download the packaged binaries (e.g., dmg files for MacOS and exe files for Windows), run them and follow the instructions.
If you want to try the development version in parallel with the stable version, we recommend to download the portable version (e.g. JabRef-X.Y.portable_windows.zip, JabRef-X.Y.portable_macos.tar.gz, or JabRef-X.Y.portable_linux.tar.gz) from builds.jabref.org/master to ensure that both versions do not conflict.
You have to change the "compatibility settings" for JabRef to "Disable scaling for high DPI settings". Further information is available at https://www.microsoft.com/surface/en-us/support/apps-and-windows-store/app-display-issues?os=windows-10.

In case you get the following error message
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.
start regedit and create the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Prefs. [source]
Use AutoHotkey and JabRef.ahk provided at koppor's autohotkey scripts.
The connection from JabRef to Libre Office requires some office related jar-archives to be present. For this, you have to install the package libreoffice-java-common.
See http://askubuntu.com/a/721387/196423 for details.
You have several Java Virtual Machines installed, and under the command line the wrong one is chosen. Have a look at the previous question that tells you how to change the virtual machine used. For Ubuntu you may also have a look at the Ubuntu page on Java.
In the background, JabRef uses JavaFX. Applications using JavaFX can be scaled via java -Dglass.gtk.uiScale=1.5 -jar <application>.jar. If you have installed JabRef via a package manager, you probably don't have a .jar file but a binary file. In this case, you need to find your JabRef.cfg in your installation folder (possibly located at /opt/JabRef/lib/app/JabRef.cfg) and add in the section [JavaOptions] the line -Dglass.gtk.uiScale=1.5. Then, restart JabRef. Try finding a value that is suitable for you. On high resolution displays, values around 1.5 seem to be reasonable.
Currently, JabRef is not signed with Apple which triggers this warning. Nonetheless, JabRef is secure to use and will not install any malware. To override the warning, use Ctrl + Click on the JabRef icon instead, then choose "open". This gives the same warning but the possibility to override it so that you can install. See the official Apple documentation for more information.
Some users with macOS Sierra have reported freezes when using JabRef. It seems this is a bug in the networking part of Java on macOS. Adding a host mapping for 127.0.0.1 seems to solve these issues.
On Mac OS X Lion, it is possible to resolve it by temporarily changing the Gate Keeper security settings under “Security&Privacy” in the system preferences to “Anywhere”. After that you can open the JabRef app. When you have opened it once, you can change the security settings back and you'll still be able to open the app.
This might be a problem related to the font you are using. You can download some other font that supports mathematical alphanumeric symbols, for example, FreeSerif or Cambria Math. A list of fonts supporting Math Unicode blocks is available at http://www.fileformat.info/info/unicode/block/mathematical_alphanumeric_symbols/fontsupport.htm.
This method is mainly for package maintainers and users who would like to build the latest snapshots of JabRef directly from the source. If you want to setup JabRef for development, follow the instructions for setting up a workspace.
To build JabRef from source, you first need to have a working Java Development Kit 13 (JDK 13) and Git installed on your system. After installing the two requirements, you open a terminal window (i.e., a command prompt) and type the following:
git clone --depth=10 https://github.com/JabRef/jabrefcd jabref./gradlew assemble./gradlew jlink
In a nutshell, you clone the latest snapshot of JabRef into jabref directory, change directory to jabref, initialize and update all the submodules (dependencies) of JabRef, assemble them to be built via JDK 13, and finally build and link them together.
The output should be the build/image subdirectory that contains the JabRef binary with all of its Java dependencies. To start JabRef, you need to run bin/JabRefMain (in Linux and MacOS) or bin/JabRefMain.bat (in Windows) under build/image subdirectory.
