java代码上传到私服,java生成 java代码 上传maven私服
功能：利用java 生成java类 ，并上传至maven私服
使用开源框架：https://github.com/square/javapoet JavaWriter分支
环境：jdk1.8 mavem
import com.squareup.javawriter.JavaWriter;
public class TestClz {
@Test
public void genrateJava() throws IOException {
enumDeclaration();
isOSLinux();
Runtime runtime=Runtime.getRuntime();
try {

} catch (IOException e) {
e.printStackTrace();
}
}
