CHANGELOG

1.2.0 (2019-09-07)

Added a --jre-path option to the exe task, allowing one to specify the path where Java is expected to be found on the end user's system.

From my understanding, the launch4j default behavior is to locate Java via the Windows registry. However, there have been reported issues around some distributions of Java (e.g. AdoptOpenJDK 11) not adding the appropriate information to the registry, and apparently using whatever java is on the PATH is not the default behavior of the executable emitted by launch4j.

According to discussions here and here, you can configure launch4j to use %JAVA_HOME%;%PATH% in the <jre><path>...</path></jre> part of the config file, and that will make it so that the executable will try to find Java via the paths specified in the %JAVA_HOME% and %PATH% Windows environment variables.

You can now do this by specifying --jre-path "%JAVA_HOME%;%PATH%" in the exe task options, and hopefully the executables you create will work if the end user has a distribution of Java that doesn't update the Windows registry appropriately.

1.1.1 (2017-10-30)

Fixed an encoding issue when running the exe task on Windows. (#2)

Thanks to Hemaolle for the fix!

1.1.0 (2016-01-21)

Both the bin and exe tasks now take a --jvm-opt flag for passing options to the Java launcher each time the executable is run.

1.0.0 (2015-11-15)

exe task produces standalone Windows executables (.exe files) from jars, using Launch4j.
Task names shortened (jar2bin -> bin, jar2exe -> exe) for the sake of simplicity.

0.1.0 (2015-11-08)

Initial release. jar2bin task produces standalone Unix/Linux executables.
