If you want to bundle and build the extension by yourself

To bundle and build the extension you can follow these steps:

1. Package the LanguageServer with maven:package.
2. Open the VS-Code Client and run npm install.
3. run npm run compile
4. install vsce npm install -g @vscode/vsce
5. run vsce package and use the .vsix File as Extension in VS Code

Known Problems and what to do

1. Currently the import statement after a selection of a type is not added. Please add it by yourself.

Logic

The Language Server in itself can be used for any Client. The Clients task is to start the Langauge Server and handle the Communication with it.

Update JavaTX Compiler Dependency as Maven Package

If you make changes in the Compiler Interface, you have to change the jar and therefore the Dependency in the Java TX Language Server You can follow this steps:

1. package the JavaTX Compiler
2. take the Jar-File and copy it into the /lib Folder
3. execute this Maven command to add the Jar in your local Repository: mvn install:install-file -Dfile=lib/JavaTXcompiler-0.1-jar-with-dependencies.jar -DgroupId=de.dhbwstuttgart -DartifactId=JavaTXcompiler -Dversion=0.1 -Dpackaging=jar
4. run maven clean, validate and install to load the new Dependency
5. you can now package the Language Server or change the code accordingly.
