異常錯誤：
當我new class的時候，提示以下錯誤：
Unable to parse template "Class"
Error message: This template did not produce a Java class or an interface
Error parsing file template: Unable to find resource 'Package Header.java'
解決方式：
方式一、
#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end
#parse("File Header.java")
public class ${NAME} {
}
