Question

Hello

I wuld like to use MAUVE ALIGNER on Ubuntu 22. I downloaded the java executable and launch it with java -jar ~/Mauve.jar but I get:

Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "."

    at java.desktop/java.awt.EventDispatchThread.run(EventDispatchThread.java:90)

I tried to install it with sudo apt-get -y install mauve-aligner; it installs but when I click on the icon in the application list, it does not launch.

I am using:

$ java -version
openjdk version "11.0.21" 2023-10-17
OpenJDK Runtime Environment (build 11.0.21+9-post-Ubuntu-0ubuntu122.04)
OpenJDK 64-Bit Server VM (build 11.0.21+9-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)

How can I launch mauve? Mauve needs "Oracle Java runtime environment". Is there a way to launch mauve from java telling it to use the right Java version but without messing with the java settings I have.

Thank you

It works but there is a problem with the JVM version.

this software tries to parse the java version:

at org.gel.mauve.gui.Mauve.hasRequiredJVM(Unknown Source)

but there is something unusual in the JVM version. Same as : https://github.com/koadman/mauve/issues/3

Mauve requires Java 8. You will need to install Java 8. Mauve comes with a script for setting the location of Java 8 and running Mauve. You will need to modify the line for JAVA8_CMD to correspond to the location of java 8 on your system.
