A collection of common Utilities i use in a lot of Projects, moved into a library to simplify keeping them up to date everywhere.
The ToMe25s-Java-Utilities.jar file should always be the latest build, as it gets build on commit by github actions.
- A Json Object
- A Json Array/List
- A Json Parser
- A simple Config Handler
- A Print Stream that can write to multiple Output Streams
- A Print Stream that can write to multiple Output Streams and has some logging/tracing capabilities
- A Print Stream that writes to a Logger
- A simple Logging Handler
- A Version Control class that can give you the currently used version of this library, and other libraries, as long as they registered their version number with this utility
- A simple Jar Extraction tool
- A simple File/Library downloader
- A tool to add Libraries to the classpath
If you want it to get downloaded on startup:
click here to see
- copy the LibraryDownloader class and the LibraryLoader class into your project.(if you copy the sources not the compiled classes you can move them to any package, but they need to all be in the same package)
- add something like
LibraryDownloader.downloadThis();
LibraryLoader.setArgs(args);
LibraryLoader.addLibsToClasspath();to the start of your main method. You can also add
com.tome25.utils.logging.LogTracer.traceOutputs(new File("LogFile.log"));// importing this would cause it to crash on loading.after the block above, to make it to Trace the System Outputs.
Note that you can't import any of this libraries classes in your main class if you do this, or else java will crash on startup, also the LibraryLoader will probably restart your software once to add the Premain-Class Attribute to the MANIFEST.MF and add a vm argument to the start command.
If you want it to be packaged into your main jar and get extracted on startup:
click here to see
- add the ToMe25s-Java-Utilites jar to your project in a way that gets it added to the finished jar.(e.g. copy it into your src directory)
- copy the JarExtractor class and the LibraryLoader class into your project.(if you copy the sources not the compiled classes you can move them to any package, but they need to all be in the same package)
- add something like
JarExtractor.extractThis(new File(MainClass.class.getProtectionDomain().getCodeSource().getLocation().getPath()));
LibraryLoader.setArgs(args);
LibraryLoader.addLibsToClasspath();to the start of your main method. You can also add
com.tome25.utils.logging.LogTracer.traceOutputs(new File("LogFile.log"));// importing this would cause it to crash on loading.after the block above, to make it to Trace the System Outputs.
Note that you can't import any of this libraries classes in your main class if you do this, or else java will crash on startup, also the LibraryLoader will probably restart your software once to add the Premain-Class Attribute to the MANIFEST.MF and add a vm argument to the start command.
If you want it to first try to download this library on startup, if that doesn't work extracts it from your jar, adds it to the classpath, and Trace the System Outputs copying all the output to a log file:
click here to see
- add the ToMe25s-Java-Utilites jar to your project in a way that gets it added to the finished jar.(e.g. copy it into your src directory)
- copy the JarExtractor, LibraryDownloader and LibraryLoader classes to your project.(if you copy the sources not the compiled classes you can move them to any package, but they need to all be in the same package)
- add something like
LibraryLoader.init(args, new File("LogFile.log"));to the start of your main method.
Note that you can't import any of this libraries classes in your main class if you do this, or else java will crash on startup, also the LibraryLoader will probably restart your software once to add the Premain-Class Attribute to the MANIFEST.MF and add a vm argument to the start command.
To build this library yourself just run mvn package in the root directory of this repo.
