Packr 4.0.0 mutiple launchers (executables) per application

1. Added an option to specify the JRE directory in the configuration file.
2. Changed the default config file name from config.json to <app name>.json
   where app name is the value of the --executable field passed to packr-all.jar.
   If the executable name is myapp (or myapp.exe on Windows) then the default config file name will be myapp.json instead
   of config.json.
   • Creating multiple launchers requires running packr multiple times or creating a config JSON via alternative means and copying and renaming the launcher to match the config name.
3. Please update your Maven and Gradle build scripts to point to https://artifactory.nimblygames.com/artifactory/ng-public.
   • Gradle will soon require HTTPS and the -snapshot and -release repository URLs are for publishing, not downloading.

Packr 3.0.3 symbolic link and pthread fixes

1. Fixed symbolic link issue for Linux and macOS JREs.
2. Fixed pthread not being available on Linux.

Packr 3.0.2 load all jre/bin Windows DLLs

1. Packr launcher now loads all DLLs in the jre/bin directory on Windows.
   • This resolves an issue on Windows where the awt.dll cannot find the Microsoft runtime libraries (MSVCP140.dll).

Packr 3.0.1 Windows DLL loading fix

1. Updated tests to use the latest versions of AdoptOpenJDK 8, 11, and 15.
2. Changed DLL loading on Windows to search in the JRE bin and server directories.
   • This should make packr more robust to Windows runtime DLL changes.
3. Fixed logging levels in ArchiveUtils
   • There was trace output logging at error level.

Packr 3.0.0 several fixes

1. Refactored code to fit better into libGdx/packr parent repository.
2. Fixed an issue where extracting an archive with duplicate entries would fail.
3. The packr-all Jar is available from GitHub packages https://github.com/libgdx/packr/packages.
4. The output directory specified by --output must be an empty directory, or a path that does not exist.
   • Packr will no longer delete the output directory and then populate it.
5. Packr will ensure that jspawnhelper has execute permissions in the bundled JRE.
   • This resolves an issue on macOS where Runtime.exec and Process.start calls would fail with java.io.IOException: Cannot run program "java": error=2, No such file or directory.
     • Reference: https://stackoverflow.com/questions/53113127/java-runtime-exec-fails-to-run/55091040
6. Updated ArchiveUtils to support POSIX permissions and symbolic links.
   • This resolves an issue with repackaged JREs losing execute permissions.
7. Alternative Maven repositories until oss.sonatype.org (Maven central) publishing is possible.

Packr 2.7.0 launcher executable fixes (temp transition back to libGDX)

1. Fixed a Gradle script error where it was bundling the release builds with debug info on Linux and macOS.
   • For Linux this reduces the executable size from ~722K to ~95K.
2. Compile with -no-pie on Linux to work around a Nautilus bug.
   • https://stackoverflow.com/questions/41398444/gcc-creates-mime-type-application-x-sharedlib-instead-of-application-x-applicati
   • https://stackoverflow.com/questions/34519521/why-does-gcc-create-a-shared-object-instead-of-an-executable-binary-according-to?noredirect=1&lq=1
3. Added compile flags /Os, /Gw, /Gy on Windows.
   • Combined with the new linker flags, this reduced the executable size.
4. Added /opt:icf, /opt:ref linker flags on Windows.
   • Combined with the new compiler flags, this reduced the executable size.
5. Updated Gradle wrapper to version 6.5.1.

Previous releases

As we work towards updating this repository, there are previous releases and notes available on my fork: https://github.com/karlsabo/packr/releases. This release is here for folks to try out the new changes while we get the code further updated to publish under libGDX URLs.

Maven artifacts

It's a work in progress to publish the artifacts to Maven Central under com.libgdx.packr. Version 3.0.0 should publish under those Maven Coordinates.
