I'm trying to clean and build my project in netbeans but it returns me the following error
/home/foxwalker/NetBeansProjects/Odontologia/nbproject/build-impl.xml:982: Existing manifest /home/foxwalker/NetBeansProjects/Odontologia/build/null875466701 is invalid
FALHA NA CONSTRUÇÃO (tempo total: 2 segundos)
while checking the source of the error:
<target depends="init,-do-jar-create-manifest,-do-jar-copy-manifest" if="do.archive+main.class.available" name="-do-jar-set-mainclass">
Erro aqui >>>> <manifest encoding="UTF-8" file="${tmp.manifest.file}" mode="update">
<attribute name="Main-Class" value="${main.class}"/>
</manifest>
</target>
I'm new and I do not understand well ...
