Maven 无法解析项目的依赖关系，找不到工件 com.mycompany.app:my-app:jar:1.0-SNAPSHOT

Question

Problem description

I'm working on a maven project which consists of 2 modules, pageobjects-users and webdriver-tests-users, I am new to java and I don't know how to fix this error: "Failed to execute goal on project pageobject-users: Could not resolve dependencies for project com.mycompany.app:pageobject-users:jar:1.0-SNAPSHOT: Could not find artifact com.mycompany.app:my-app:jar:1.0-SNAPSHOT -> [Help 1] "

this problem occurs when I use mvn package or mvn package install commandline, everything works fine on IntelliJ IDEA

Answer

I got it solved by creating third module, after that I moved my TestRunner.class to the module and added dependency on it.
