/java_playing_with_classpath

Generates, compiles, and runs java for playing with classpath

Primary LanguageShell

playing_with_classpath

Generates, compiles, and runs code to demonstrate java build tools including gradle. This includes JNI extensions built in C and rust. Can be run from any directory.

Main scripts

clean

Clean the source code and build artifacts (except the rust target directory because that would be slow).

generate [configuration_script]

Generate the source code and directory structure. Can pass a parameter of configuration script for naming. e.g.

root_directory="."
configuration_name='playing_with_classpath'
package_name='com.me.example'
jar_name='example'
declare -a typical_java_classes
typical_java_classes=( 'Foo' 'Bar' )

compile

Compile

  • the rust source (release and debug)
  • the c source (release and debug)
  • the java source code into .class files
  • a .jar file containing the java .class files, and rust and c release and debug jni dynamic libraries.

showinfo

Dump some information including jar file.

run

Run the resulting jar file both by calling java directly, and via ./gradlew run. The jar's behaviour is manipulated by specifying system properties for which jni library to use, and running debug or release.

Additional scripts

templatise [TARGET_DIRECTORY]

Aftering generating code in this directory, use it as the template for a project in another directory (passed as a parameter). Generated compile scripts build c/rust jni. java should be compiled by running ./gradlew build. Generated run script runs with gradle.

all

Run all the steps (apart from clean).

Common Usage.

Creating a new project

cp project_configuration my_project_configuration
# Edit my_project_configuration as necessary
./clean
./generate my_project_configuration
./templatise ../my_new_project
cd ../my_new_project
./compile
./gradlew build
./run

Running example project from scratch

./clean
./generate
./compile
./run
./showinfo
