Error: Could not find or load main class com.company.Main code example
Example 1: Error: Could not find or load main class mina.calc.MinaCalculator in module mina
Example 2: > Task :run FAILED Error: Could not find or load main class Caused by: java.lang.ClassNotFoundException:
Check your build.gradle file and update the application block:
application {
mainClassName = 'packageName.MainClass'
}
Example 3: Error: Could not find or load main class -Djava.library.path=.home.hdoop.hadoop-3.3.0.lib.native
Sounds silly, but if you've copied .bashrc lines from somewhere
check that the quotation marks are like this:
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib/native"
and not like this
export HADOOP_OPTS=”-Djava.library.path=$HADOOP_HOME/lib/native”
...took me some time
Example 4: eclipse Error: Could not find or load main class main java.lang.ClassNotFoundException
