使用oracle服务器JRE 8在docker中运行java可以'；无法找到或加载主类

我正在尝试使用官方的oracle serverjre映像在docker中运行java应用程序。我使用gradle构建它（构建得很好），然后构建docker容器（也很好），但当我尝试启动它时，它会显示“main-server|1 |错误：无法访问jarfile/main server.jar”。目前，应用程序只包含一个main方法，其中包含println

Dockerfile：

FROM store/oracle/serverjre:8
WORKDIR /home

COPY ./build/libs/main-server-1.0.jar /home/main-server.jar

ENTRYPOINT ["java", "-jar", "/main-server.jar"]

build.gradle：

apply plugin: "java"

version = "1.0"
jar {
    manifest {
        attributes (
            "Implementation-Title": "Main Server",
            "Implementation-Version": version,
            "Main-Class": "src/main/java.com.getsendus.server.Application"
        )
    }
}

repositories {
    maven {
        url "http://central.maven.org/maven2/"
    }
}

dependencies {
    compile "org.mongodb:mongodb-driver-async:3.9.0"

    compile "javax.servlet:javax.servlet-api:3.1.0" 
    testCompile "junit:junit:4.12"
    compile files("${System.getProperty('java.home')}/../lib/tools.jar")
}

Application.java：

package com.getsendus.server;

public class Application {

    public static void main(String[] args) {
        System.out.println("Main Server Running");
    }
}
