How to build and run the project

[gongzelong0718]

I clone the project. Could anyone tell me how to build and run the project? For example, I want to use ls command line.

Plus, I imported the project using IDEA for both /unix4j/unix4j-core and /unix4j. But IDE could not resolve LsArguments. Anyone know why?

You have to build it with maven. The reason that some classes are not found is that they are generated during the build.

Run “mvn clean install’ from command line or use import pom in Intellij and then build from there.

Sorry, I run mvn clean install in the directory /home/zelongg/Code/unix4j. It shows in the Terminal:

Could you tell me what I should do next?

I also tried build project, but it fails

use import pom in Intellij and then build from there What directory should I choose when I want to open the pom.xml, /unix4j/unix4j-core or /unix4j?

I mainly want to see how to implement ls command line.

Oh, I close the 2 existing projects. And open the pom.xml in /unix4j, and then select build -> build project.

It shows in Message:

Information:Using javac 1.8.0_131 to compile java sources
Information:Modules "unix4j-command", "unix4j", "unix4j-perf" were fully rebuilt due to project configuration/dependencies changes

It seems that it build successfully. How amazing!

After I build successfully using your second way. I tried to use ls command line. I notice that in the wiki, it says ExampleTest.java does that. According to this file unix4j-examples/README.txt

So I run and got this:

Should I check the document https://www.jetbrains.com/help/idea/maven.html?

Sorry the pom was pointing to the wrong version.

Update to newest version (git pull) then try again. You may need to rebuild unix4j first to rebuild the snapshot version before you build the examples project.

Thanks, Marco, it works.

For the record, I wrote down the way of building:
