I have built many times with the new jpackage, but actually just now tried to install the package built by it.
The new jpackage adds a lot of Requires to the built RPM package. We had the same problem with the old javapackager. Its default RPM spec file had a lot of Requires that made it difficult for us to install our package on different Linux distributions. We circumvented this by packaging the application image with the Gradle ospackage plugin for RPM and DEB packages. Only the last one of these requires is actually in our RPM spec file provided with --resource-dir. I cannot even install the package on the system I built it, because it cannot find libavcodec-ffmpeg.so.56 For OpenSUSE Leap 15.1, my Linux distribution there is no package that provides the libavcodec-ffmpeg. Are all these Requires actually necessary for running a JavaFX application on Linux? As mentioned we had packaged our JavaFX 8 application with Gradle ospackage plugin without all these Requires, and it has worked fine on RPM Linux distributions. ld-linux-x86-64.so.2()(64bit) ld-linux-x86-64.so.2(GLIBC_2.3)(64bit) libGL.so.1()(64bit) libX11.so.6()(64bit) libXext.so.6()(64bit) libXi.so.6()(64bit) libXrender.so.1()(64bit) libXtst.so.6()(64bit) libasound.so.2()(64bit) libasound.so.2(ALSA_0.9)(64bit) libasound.so.2(ALSA_0.9.0rc4)(64bit) libavcodec-ffmpeg.so.56()(64bit) libavcodec-ffmpeg.so.56(LIBAVCODEC_FFMPEG_56)(64bit) libavcodec.so.54()(64bit) libavcodec.so.54(LIBAVCODEC_54)(64bit) libavcodec.so.56()(64bit) libavcodec.so.56(LIBAVCODEC_56)(64bit) libavcodec.so.57()(64bit) libavcodec.so.57(LIBAVCODEC_57)(64bit) libavformat-ffmpeg.so.56()(64bit) libavformat-ffmpeg.so.56(LIBAVFORMAT_FFMPEG_56)(64bit) libavformat.so.54()(64bit) libavformat.so.54(LIBAVFORMAT_54)(64bit) libavformat.so.56()(64bit) libavformat.so.56(LIBAVFORMAT_56)(64bit) libavformat.so.57()(64bit) libavformat.so.57(LIBAVFORMAT_57)(64bit) libawt.so()(64bit) libawt_xawt.so()(64bit) libc.so.6()(64bit) libc.so.6(GLIBC_2.11)(64bit) libc.so.6(GLIBC_2.14)(64bit) libc.so.6(GLIBC_2.15)(64bit) libc.so.6(GLIBC_2.17)(64bit) libc.so.6(GLIBC_2.2.5)(64bit) libc.so.6(GLIBC_2.3)(64bit) libc.so.6(GLIBC_2.3.2)(64bit) libc.so.6(GLIBC_2.3.4)(64bit) libc.so.6(GLIBC_2.4)(64bit) libc.so.6(GLIBC_2.6)(64bit) libc.so.6(GLIBC_2.7)(64bit) libcairo.so.2()(64bit) libdl.so.2()(64bit) libdl.so.2(GLIBC_2.2.5)(64bit) libfreetype.so()(64bit) libfreetype.so.6()(64bit) libgdk-3.so.0()(64bit) libgdk-x11-2.0.so.0()(64bit) libgdk_pixbuf-2.0.so.0()(64bit) libgio-2.0.so.0()(64bit) libglib-2.0.so.0()(64bit) libgmodule-2.0.so.0()(64bit) libgobject-2.0.so.0()(64bit) libgstreamer-lite.so()(64bit) libgthread-2.0.so.0()(64bit) libgtk-3.so.0()(64bit) libgtk-x11-2.0.so.0()(64bit) libjava.so()(64bit) libjli.so()(64bit) libjvm.so()(64bit) libjvm.so(SUNWprivate_1.1)(64bit) libm.so.6()(64bit) libm.so.6(GLIBC_2.15)(64bit) libm.so.6(GLIBC_2.2.5)(64bit) libnet.so()(64bit) libpango-1.0.so.0()(64bit) libpangoft2-1.0.so.0()(64bit) libpthread.so.0()(64bit) libpthread.so.0(GLIBC_2.2.5)(64bit) libpthread.so.0(GLIBC_2.3.2)(64bit) librt.so.1()(64bit) librt.so.1(GLIBC_2.2.5)(64bit) libverify.so()(64bit) libz.so.1()(64bit) rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(FileDigests) <= 4.6.0-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rpmlib(PayloadIsXz) <= 5.2-1 rtld(GNU_HASH) xdg-utils
