Error: Could not find or load main class s open txt file code example
Example 1: > 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 2: 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
