Arch Linux User Repository

@nomisge Can't you take over the project and make it official? I'm not sure whether @chetgurevitch is still maintaining the project. It has been more than half a year since I flagged the project.

I'd really appreciate the project to continue.

I did following changes locally to also have mime-types set correctly, to be able to open greenfoot when project.greenfoot is clicked.

Changed greefoot:

#!/bin/sh
if [ -e /usr/lib/jvm/java-11-openjfx/lib ]; then
        JAVAFX_HOME=/usr/lib/jvm/java-11-openjfx/lib
else
        JAVAFX_HOME=/usr/lib/jvm/java-11-openjdk/lib
fi

JAVAFX_CP="$JAVAFX_HOME/javafx.base.jar:$JAVAFX_HOME/javafx.controls.jar:$JAVAFX_HOME/javafx.fxml.jar:$JAVAFX_HOME/javafx.graphics.jar:$JAVAFX_HOME/javafx.media.jar:$JAVAFX_HOME/javafx.swing.jar:$JAVAFX_HOME/javafx-swt.jar:$JAVAFX_HOME/javafx.web.jar"

archlinux-java-run -a 11 -b 11 -- -Djavafx.embed.singleThread=true \
        -Dawt.useSystemAAFontSettings=on \
        -cp /opt/greenfoot/bluej.jar:/usr/lib/jvm/default/lib/tools.jar:$JAVAFX_CP bluej.Boot \
        -greenfoot=true \
        -bluej.compiler.showunchecked=false \
        -greenfoot.url.javadoc=file:///usr/share/doc/greenfoot/API \
        -javafxpath=$JAVAFX_CP \
        "$@"

Changed greenfoot.desktop

[Desktop Entry]
Encoding=UTF-8
Version=1.0

Comment=A simple Java IDE and animation framework
Categories=Application;Development;
Exec=greenfoot %u
MimeType=application/x-greenfoot.package
Icon=greenfoot
Terminal=false
Type=Application
StartupWMClass=bluej.Boot$App

Added greenfoot.xml

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="application/x-greenfoot.package">

         <comment xml:lang="de">Greenfoot Paket</comment>
         <glob pattern="*.greenfoot"/>
  </mime-type>
</mime-info>

Added greenfoot.install

post_install() {
    if test -x /usr/bin/update-mime-database usr/share/mime &> /dev/null; then update-mime-database usr/share/mime &> /dev/null; fi
}

post_upgrade() {
    post_install
}

pre_remove() {
    if test -x /usr/bin/update-mime-database usr/share/mime &> /dev/null; then update-mime-database usr/share/mime &> /dev/null; fi
}

Changed source and sha256sum lines in PKGBUILD and added

install -Dm644 "${pkgname}.xml" "${pkgdir}/usr/share/mime/packages/${pkgname}.xml"

@chetgurevitch Have you found time to verify that the modifications are working? Here is the code of the greenfoot file:

!/bin/sh

if [ -e /usr/lib/jvm/java-11-openjfx/lib ]; then JAVAFX_HOME=/usr/lib/jvm/java-11-openjfx else JAVAFX_HOME=/usr/lib/jvm/java-11-openjdk fi

JAVAFX_CP="$JAVAFX_HOME/lib/javafx.base.jar:$JAVAFX_HOME/lib/javafx.controls.jar:$JAVAFX_HOME/lib/javafx.fxml.jar:$JAVAFX_HOME/lib/javafx.graphics.jar:$JAVAFX_HOME/lib/javafx.media.jar:$JAVAFX_HOME/lib/javafx.swing.jar:$JAVAFX_HOME/lib/javafx-swt.jar:$JAVAFX_HOME/lib/javafx.web.jar"

archlinux-java-run -a 11 -b 11 -- -Dawt.useSystemAAFontSettings=on \ -cp /opt/greenfoot/bluej.jar:/usr/lib/jvm/default/lib/tools.jar:$JAVAFX_CP bluej.Boot \ -greenfoot=true \ -bluej.compiler.showunchecked=false \ -greenfoot.url.javadoc=file:///usr/share/doc/greenfoot/API \ -javafxpath="$JAVAFX_HOME" \ "$@"

The new version 3.6.1 (6 Dec 2019) works with the modifications by @foer. Tested it on 8 Dec 2019. No issues like the ones mentioned in my comment on 8 Nov.

Thanks a lot to all the people who contribute to this aur, especially to @chetgurevitch

Awesome. Works without any issues now.

@chetgurevitch Could you please alter the file accordingly? That would be great.

Thanks a lot to everyone.

Greenfoot starts but then gives that error mentioned by @teacher4711 when opening a scenario. Three modifications in /usr/bin/greenfoot have to be done:

1. add -javafxpath="$JAVAFX_HOME" to the startup parameters
2. change pathline to JAVAFX_HOME=/usr/lib/jvm/java-11-openjdk
3. add the lib-Parts to the JAVAFX_CP= line

In all it then looks like:

!/bin/sh

if [ -e /usr/lib/jvm/java-11-openjfx/lib ]; then JAVAFX_HOME=/usr/lib/jvm/java-11-openjfx/lib else JAVAFX_HOME=/usr/lib/jvm/java-11-openjdk fi

JAVAFX_CP="$JAVAFX_HOME/lib/javafx.base.jar:$JAVAFX_HOME/lib/javafx.controls.jar:$JAVAFX_HOME/lib/javafx.fxml.jar:$JAVAFX_HOME/lib/javafx.graphics.jar:$JAVAFX_HOME/lib/javafx.media.jar:$JAVAFX_HOME/lib/javafx.swing.jar:$JAVAFX_HOME/lib/javafx-swt.jar:$JAVAFX_HOME/lib/javafx.web.jar"

archlinux-java-run -a 11 -b 11 -- -Dawt.useSystemAAFontSettings=on \ -cp /opt/greenfoot/bluej.jar:/usr/lib/jvm/default/lib/tools.jar:$JAVAFX_CP bluej.Boot \ -greenfoot=true \ -bluej.compiler.showunchecked=false \ -greenfoot.url.javadoc=file:///usr/share/doc/greenfoot/API \ -javafxpath="$JAVAFX_HOME" \ "$@"

It seems Greenfoot is having trouble finding certain JavaFX classes, notably KeyCombination as @teacher4711 has already mentioned. It may be that Greenfoot is having trouble dealing with the external packages, but I'm no expert.

Am I missing something? I did a clean install of ArchLinux, built greenfoot with all its dependencies and starting it results in the following error message(s):

Exception in thread "Thread-0" java.lang.NoClassDefFoundError:

javafx/scene/input/KeyCombination at greenfoot.core.GreenfootLauncherDebugVM$1.run(GreenfootLauncherDebugVM.java:80)

Caused by: java.lang.ClassNotFoundException: javafx.scene.input.KeyCombination at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:581) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521) ... 1 more

There is no such error when installing the jar-Version from the official website.

@teacher4711 thanks for pointing that out, they started bundling those with the 3.6 update for some reason. It isn't in bluej as you noted nor was it in any previous versions of greenfoot. Also violates debian packaging guidelines. Package size is back down to 17mb and I might end up switching the package we download to the generic java one to save on the download as well.

Thanks for the hard work and the fact that you maintain the package. Greenfoot works flawlessly now.

Just one question: Greenfoot is roughly 200 megs in size, BlueJ 15, and both rely on JDK 11 and JavaFX, don't they? Would it be possible to strip the JDK and JavaFX from /opt/greenfoot and make Greenfoot rely on the packages provided by Arch Linux to reduce size?
