问题描述
当我将简单项目部署到Heroku时，出现了Maven插件错误 Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin
我的代码非常简单，它是一个实体类和restController类，当我在PC上运行项目时，它可以运行，但部署失败。 我的班级
package com.hosting.hostingTest;
public class BucketList {
private long id;
private String name;
public BucketList(long id,String name) {
this.id = id;
this.name = name;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
