问题描述
我正在使用NetBeans IDE中的CloudSim项目,我需要将
org.apache.common
导入到我的项目中。
我已按照在我的Windows 10上安装Java jdk和NetBeans。然后我按照以下步骤将CloudSim项目添加到NetBeans:
1. file - >新项目 - > Java与Ant - >带有现有源的Java项目
2.为项目定义名称和文件夹,路径为:`\ CloudSim_Tutorial`
3.添加现有源我添加了CloudSim文件夹as我的来源
4.完成
该项目抛出错误:
包org.apache.common.math3.linear不存在
对于某些java文件。所以我在网上搜索并做了以下事情:
1.下载commons-math3-3.2-bin二进制文件
2.解压缩我项目文件夹中的zip文件, `\ CloudSim_Tutorial`
3.右键点击项目名称 - >属性
4.从弹出窗口中选择的库
5.在`classPath`中单击`+`符号
6.选中`commons-math3-3.2.jar`文件 - >好的
仍然会抛出错误。
导致错误的代码:
import org.apache.commons.math3.linear.Array2DRowRealMatrix;
错误:
包org.apache.commons.math3.linear不存在。
我尝试了什么:
我看过很多教程但是我无法成功。
I'm working on CloudSim project in NetBeans IDE and I need to import
org.apache.common
into my project.
I have followed youtube to install Java jdk and NetBeans on my windows 10. Then I followed steps below to add CloudSim project to NetBeans:
1. file -> new project -> Java with Ant -> Java Project with Existing Source
2. defined name and folder for project, the path is: `\CloudSim_Tutorial`
3. to add existing source I added CloudSim folder as my source
4. finish
The project throw an error that:
Package org.apache.common.math3.linear does not exist
for some java files. So I searched on the web and did the following:
1. download commons-math3-3.2-bin binary file
2. extracted the zip file in my project folder, `\CloudSim_Tutorial`
3. right click on project name -> properties
4. selected Libraries from pop-up window
5. in `classPath` clicked on `+` sign
6. selected the `commons-math3-3.2.jar` file -> Ok
It still throw the error.
The code causing error:
import org.apache.commons.math3.linear.Array2DRowRealMatrix;
Error:
Package org.apache.commons.math3.linear does not exist.
What I have tried:
I have see many tutorials but I couldn't make it.
