Java轻量级插件框架，可实现动态加载，执行，卸载外部插件(支持jar zip)

The current minimum Java version required to build PF4J should be 9, but the runtime Java version can be 8 since the artifact is a multi-release jar.

https://github.com/pf4j/pf4j/releases/tag/release-3.4.0

run-demo.sh
运行脚本需要修改下
mv pf4j-demo-app-*-SNAPSHOT.jar pf4j-demo.jar
改成
mv pf4j-demo-app-3.4.0.jar pf4j-demo.jar

jdk8 运行报错
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project pf4j: Fatal error compiling: 无效的标记: --release
Fatal error compiling: 无效的标记: --release

jdk11 ok
运行之前设置下 JAVA_HOME
export JAVA_HOME=/PATH/jdk11/Contents/Home

注意 plugin1 依赖了  apache commons-lang ，会把他一并打进去 ，因此打出来的jar包比较大

jar tvf pf4j-demo-plugin1-3.4.0-all.jar




  
demo-dist 目录下运行
java -jar pf4j-demo.jar
在jdk8 和 jdk11  运行ok
