I import maven project from github to eclipse.

Export > Projects from git > Clone URI > Fill params > Next > Import as general project

After that, I configure project to maven. And all its ok, I can build it. BUT!

If I edit code and write some error, error doesn´t display. Why?

You didn't tell us which View the picture shows. If it where the Package Explorer, then the icons would indicate that you have not configured any source folders (Project Properties > Java Build Path) The Eclipse Java compiler will only analyse .java files within known source folders.

Yes, build path not configured. But I can´t configured build path. In the Picture, you can seen No actions avalibe. How can I add resources to build path? In other project build path show normally.

I've never seen that sub menu empty, so no quick guess what might be amiss.
You may want to paste your .project and .classpath files to show how the project is configured.

I also noticed, that you have what looks like nested projects, which will not be recognized as such by Eclipse.
Things might already clear up if you just say "Import ... > Existing Maven Projects " and select all those sub projects.
(In fact, if the toplevel project is just a pom-project that could also explain why m2e doesn't allow defining a build path here).

Only .project I have in root folder, there:

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
	<name>uSkyBlock</name>
	<comment></comment>
	<projects>
	</projects>
	<buildSpec>
		<buildCommand>
			<name>org.eclipse.m2e.core.maven2Builder</name>
			<arguments>
			</arguments>
		</buildCommand>
	</buildSpec>
	<natures>
		<nature>org.eclipse.m2e.core.maven2Nature</nature>
	</natures>
</projectDescription>

Classpath is on subfolders, uSkyBlock-API, Core ...

For exmple. .project and classpath from uSkyBlock-Core:

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
	<name>uSkyBlock-Core</name>
	<comment></comment>
	<projects>
	</projects>

		</buildCommand>
		<buildCommand>
			<name>org.eclipse.m2e.core.maven2Builder</name>
			<arguments>

		</buildCommand>
	</buildSpec>
	<natures>
		<nature>org.eclipse.jdt.core.javanature</nature>
		<nature>org.eclipse.m2e.core.maven2Nature</nature>
	</natures>
</projectDescription>

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" output="target/classes" path="src/main/java">
		<attributes>
			<attribute name="optional" value="true"/>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>

	<classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources">

		</attributes>
	</classpathentry>

		</attributes>
	</classpathentry>
	<classpathentry excluding="**" kind="src" output="target/test-classes" path="src/test/resources">

			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7">
		<attributes>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
		<attributes>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="output" path="target/classes"/>
</classpath>

If I click to uSkyBlock (from git) and select Import > Existing maven projects > select all folders > in package Explorere I can see projects uSkyBlock-Core and more, and display errors. But, if developer update project on github, update my project in package explorer too?

So it seems to be working for you now, right? Remember, Java errors are only displayed in Java projects in Eclipse. The root thing is not a Java project, the sub-folders are not known as Eclipse projects until "Import > Existing maven projects".
