Java not found

1

Builds my snap ok but when I go to run it I get “Java not found” with the following Snapcraft Yaml.

name: highlighterpdf
title: HighlighterPdf
version: 1.0.2
summary: Highiight the text in a Pdf.
description:
        HighlighterPdf  is a free and open source software application that you can use to 
        highlight text in your pdf document. You can select text in a colour of your choice        
        and then save it.
base: core18

confinement: devmode

apps:
 highlighterpdf:
   extensions:
         - gnome-3-28
   command: desktop-launch ./highlighterpdf.sh
   environment:
         JAVA_HOME: $SNAP/usr/lib/jvm/java-1.8.0-openjdk
         PATH: $JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
         plugs:
               -home

you’re staging openjdk 11, so the path to java is:

$SNAP/usr/lib/jvm/java-11-openjdk-amd64/bin/java

You likely want to adjust your JAVA_HOME and PATH variables accordingly:

apps:
  highlighterpdf:
    ...
    environment:
      JAVA_HOME: $SNAP/usr/lib/jvm/java-11-openjdk-amd64
      PATH: $JAVA_HOME/bin:$PATH # there is no ./jre folder

You will also want to fix your yaml formatting errors. Your plugs block is indented too far and the individual plugs in the list should have a space after the “list item” indicator (i.e. the hyphen “-” character).

Also, when using the gnome extension you do not need to specify desktop-launch on your app’s command setting:

apps:
  highlighterpdf:
    extensions: [gnome-3-28]
    command: highlighterpdf.sh # make sure to include any relative paths

If your shell script is in bin then you’ll want to modify the command to bin/highlighterpdf.sh.

Thank you so much for your kind help Daniel.

I made the changes you advised to do now I have more problems.

When I do not use desktop-launch in my command I get:

“The specified command ‘highlighterpdf.sh’ defined in the app ‘highlighterpdf’ is not executable.”

But I have set the permissions of highlighterpdf.sh to executable.

And when I set the plugs back to where they should be I get:

“The ‘apps/highlighterpdf/environment/plugs’ property does not match the required schema: [‘home’, ‘network’, ‘cups-control’] is not of type ‘number’ or [‘home’, ‘network’, ‘cups-control’] is not of type ‘string’”

Thanks for looking
