Arch Linux User Repository

Besides all the fixes/improvements suggested, there is a new upstream version: https://www.bluej.org/download/files/BlueJ-linux-500.deb

I flagged it out of date and requested to orphan the package, cause I would like to continue maintaining it, if @chetgurevitch wont.

Application works, but many of its pop-up dialogs have zero size, showing up as just a vertical line. Doesn't happen for "Open Editor" and such, but for "Delete" on a class, "Tools > Teams > Checkout Project", and various important functionality this happens. Weirdly it sometimes randomly works, but I have yet to figure out the pattern.

Any ideas?

Exception in thread "main" java.lang.NoClassDefFoundError: javafx/application/Application

Although It is installed. Java-13-OpenJDK, Java-11-OpenJDK, both give same error. Could anyone help please?

To be able to have bluej automatically open when clicked on project.bluej file, please add a mime type. I realized it with following additions:

I included a bluej.install with following content:

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
}

Added bluej.xml

<?xml version="1.0" encoding="UTF-8"?>
 <mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="application/x-bluej.package">
         <comment>BlueJ Package</comment>
         <comment xml:lang="de">BlueJ Paket</comment>
         <glob pattern="*.bluej"/>
  </mime-type>
</mime-info>

And changed bluej.desktop

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Name=BlueJ
Comment=A simple powerful Java IDE
Categories=Application;Development;
Exec=bluej %u
MimeType=application/x-bluej.package;
Icon=bluej
Terminal=false
Type=Application
StartupWMClass=bluej.Boot$App

And finally updated source and sha256sums lines in PKGBUILD and added:

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

I just installed the package on arch linux running the 5.3.11 kernel, however no fonts are being rendered in the program. If I hover around the header I can see submenus however none of the text is being rendered.

[ SOLVED ] Up to now, I tried several (re-)installs with regard to java/javafx under Manjaro - no success. I (still) receive the following errors when starting BlueJ:

Any ideas? Help really appreciated!!

Starting from scratch, re-installing all dependencies, BlueJ runs again.

I thought I was stuck but Jakobchs comment helped me out. Apparently if BlueJ seems to be stuck loading it opens another window where you need to confirm something but the windows is too small to see something and not resizable. Just hit enter.

@chetgurevitch Thank you for your quick reply and help. Unfortunately, I couldn't figure out anything I could install additionally or change. I posted the output of

$ pacman -Fl java11-openjfx on https://pastebin.com/DzGu8qJ3

and $ archlinux-java status results in

java-11-openjdk java-12-jdk (default) java-13-openjdk java-8-jre/jre

(as written in my first post)

The installed Bluej-Version is 4.2.2-1.

Appreciate your help!

@chromanju can't reproduce, make sure you're using the latest PKGBUILDs (4.2.1-5 and 3.6.0-3), you have java11-openjfx installed, and your system is fully up to date. If you're still experiencing the issue please post the output of

$ pacman -Fl java11-openjfx

and

$ archlinux-java status

edit: about to update bluej to 4.2.2, would be best if you could test with this version
