无法在Groovy中成功导入类？ [英] Could not successfully Import class in Groovy?

问题描述

我在一个名为business.groovy的文件中创建了名为供应商和地址的两个类（即，我使用名称 business ）
在同一个文件夹中，我创建了另一个groovy代码，用于导入业务包并使用Vendor类属性（Vendor是业务包中的类）。但是，当我尝试在该groovy脚本中为供应商创建对象时，它会抛出错误，指出：
$ b

/ home / Anto / Groovy / pakg / Imports.groovy：2：无法解决类供应商
@第2行第13列。
def canoo = new Vendor（）

我需要做什么？

以下是我创建的文件：
business.groovy

 包业务
类供应商{
公共字符串名称
公共字符串产品
公共地址=新地址（ ）
} 
 class地址{
 public String street，town，state 
 public int zip 
} 
  

impotTesting.groovy

  import * 
 def canoo = new Vendor（）
 canoo.name ='Canoo Engineering AG'
 canoo.product ='UltraLightClient（ULC）'
  

当我尝试使用 groovy importTesting 命令执行 importTesting.groovy 文件时，我得到了前面提到的错误！

解决方案

我建议您使用一些构建工具，如 Ant 或 Gradle 或IDE，如 IntelliJ IDEA 来控制你的类路径/编译/运行时需求。

编辑：应该是这样的：

  baseDir / business /business.groovy 
 baseDir / impotTesting.groovy 
  

您编译的类也应该类似目录结构：

  baseDir / business / business * .class 
 baseDir / impotTesting * .class 
  

然后您的baseDir应该添加到CLASSPATH中。

I created a two class named Vendor and Address in one file called business.groovy(that is I created package using the name business) And in the same folder I created another groovy code that imports the business package and make use of Vendor class attributes(Vendor is class in business package). But when I try to create a object for Vendor in that groovy script, it throwing error stating that:

/home/Anto/Groovy/pakg/Imports.groovy: 2: unable to resolve class Vendor @ line 2, column 13. def canoo = new Vendor()

What do I have to do? Where did I go wrong?

These are the files I created: business.groovy

package business
class Vendor {
public String name
public String product
public Address address = new Address()
}
class Address {
public String street, town, state
public int zip
}

impotTesting.groovy

import business.*
def canoo = new Vendor()
canoo.name = 'Canoo Engineering AG'
canoo.product = 'UltraLightClient (ULC)'

And when I try to execute the importTesting.groovy file by using groovy importTesting command, I get the error as I mentioned before!

解决方案

I would suggest you to either use some build tool like Ant or Gradle, or IDE like IntelliJ IDEA to control your classpath/compilation/runtime needs.

EDIT: It should be like that:

baseDir/business/business.groovy
baseDir/impotTesting.groovy

Your compiled classes should also resemble the same directory structure:

baseDir/business/business*.class  
baseDir/impotTesting*.class

Then your baseDir should be added to the CLASSPATH.
