“Clean and build” results in this error :

..\nbproject\build-impl.xml:987: Manifest attribute names must not contain '.'

Here is build-impl.xml:

<manifest file="${tmp.manifest.file}" mode="update"> <--- 987 line
    <attribute name="java.net.myroshnychenko.Main-Class" value="${main.class}"/>
</manifest>

Thank you.

attribute name=“Main-Class” value="${main.class}"

The problem is the "."s in the actual attribute name.
