I have a spring boot project here: https://github.com/jcasbin/jcasbin-springboot-plugin. I encountered the following error in Travis CI:
3.43s$ ./mvnw install -DskipTests=true -Dmaven.javadoc.skip=true -B -V
Picked up _JAVA_OPTIONS: -Xmx2048m -Xms512m
Error: Could not find or load main class org.apache.maven.wrapper.MavenWrapperMain
The command "eval ./mvnw install -DskipTests=true -Dmaven.javadoc.skip=true -B -V " failed. Retrying, 2 of 3.
It seems that the
mvnw command fails. This file is generated by my IDE: IntelliJ IDEA 2018.1. I don’t know what it is used for and why does it fail?
I already fired an issue in Spring Boot’s github issues here, but Spring project said it’s Maven wrapper’s issue and pointed me here. I don’t quite understand what it means. Is it a Maven bug? How to fix the error then?
