These are the instructions for the generic BlueJ installer (the installer "for other operating systems"). This installer can be used on most Unix-like operating systems as well as Mac OS X and Windows. However, it is generally preferable to use the "native" installer when available.
The generic installer requires that a Java JDK be installed separately. There are two possibilites depending on the version of BlueJ:
Run the following command:
java -jar <path-to-bluej-installer>
... replacing <path-to-bluej-installer> with the correct path to the installer .jar file that you downloaded.
If you receive a "command not found" or similar error, you may need to specify the full path to the Java executable. For example:
"C:\Program Files\Java\jdk1.8.0_144\bin\java.exe" -jar "C:\Users\Sarah\Downloads\bluej-411.jar"
(this example is for Windows; other operating system paths normally use '/' as a path separator!).
To run BlueJ:
On Windows:
Change into the directory where you installed BlueJ:
cd <path-to-bluej-installation>
... replacing <path-to-bluej-installation> with the path you chose to install BlueJ to.
bluej.bat
On other operating systems:
Change into the directory where you installed BlueJ:
cd <path-to-bluej-installation>
... replacing <path-to-bluej-installation> with the path you chose to install BlueJ to.
./bluej
