Hot fix: improve robustness of setting Java environment in the current session with either use_java() or java_quick_install(). See bug fix below.
Bug fix: Setting Java environment via rJava::.jniInitialized() rendered impossible changing Java version for rJava-dependent packages, because it somehow pre-initialised rJava
Breaking change: java_check_version_cmd() and java_check_version_rjava() now return detected Java version instead of TRUE/FALSE
New function use_java() to download, install and set Java from cache for the current sesssion, without touching the current project/working directory. This is intended for use with targets and callr.
New vignette on using the package with targets' and 'callr
Updated documentation with clearer instructions on cache folder cleanup before removing the package
Depends on R > 4.0 to be able to write to the package cache directory without extra user warning. Cache cleanup and management functions are provided, as well as the documentation in both README and vignettes.
Improved documentation
Better handling of cache directory
