I'm trying to get javadocs for my classes directly from console with following code javadoc -sourcepath ./src/main java.packageName. Those classes have dependencies on external libraries (e.g junit.framework). This code is easy to compile from IntelliJ IDEA or via mvn clean install, but when I'm trying to create javadocs I face the problem that external classes and packages cannot be recognized (e.g. error: package junit.framework does not exist). Same problem occurs with JDK 8 as well, but there those are warnings and javadocs are generated anyway.
There are two approaches you could take to get the javadocs to build from the command line:
Add the maven-javadoc-plugin to your project's POM file so that you can use (for example) mvn javadoc:javadoc to generate the javadocs. See the plugin documentation for more details.
Run javadoc directly with the correct command-line arguments.
I suspect that there are a couple of reasons why your current attempt is failing:
You appear to be generating javadocs for your src/test tree. That may be unintentional.
(If the above "error: ..." is coming from the src/main javadoc generation, I'm puzzled why your src/main source code is referring to the junit.framework package. It could do, but production code wouldn't normally depend on a test framework.)
You need to use a -classpath option to tell javadoc where to find the external libraries are.
