java - 嵌入式 Tomcat 8 war maven 上的 "File name too long error"

Question

我一直在寻找嵌入式 tomcat 版本 8+，所以我从本教程中找到了一个:https://www.youtube.com/watch?v=VbXb73bU5N4 .它在我的 Windows 上运行良好，现在当我在 Linux 上运行时遇到了一些问题。我一直在寻找答案，但没有找到任何东西。如果 class.path.java 是导致文件名太长的问题，我该怎么办？

错误信息:

和我的启动器

package com.mateusz.tomcat.embedded;

import org.apache.catalina.Context;
import org.apache.catalina.Host;
import org.apache.catalina.startup.Tomcat;

import java.io.File;

public class Launcher {
    public static void main(String[] args) {
        Launcher launcher = new Launcher();
        try {
            launcher.startServer();
        } catch (Exception e) {
            System.out.println("couldn't start the server");
        }
    }

    private void startServer() throws Exception {
        File war = new File(System.getProperty("java.class.path"));
        Tomcat tomcat = new Tomcat();
        tomcat.setPort(8888);
        tomcat.setBaseDir(System.getProperty("user.dir"));
        System.out.println("war: " + war);

        Host host = tomcat.getHost();
        host.setAppBase(System.getProperty("user.dir"));
        host.setAutoDeploy(true);
        host.setDeployOnStartup(true);
        Context appContext = tomcat.addWebapp(host, "/embedded", war.getAbsolutePath());
        System.out.println("Deployed " + appContext.getBaseName() + " as " + appContext.getDocBase());

        tomcat.start();
        tomcat.getServer().await();
    }
}

我已经通过改变一条车道解决了这个问题。

File war = new File(System.getProperty("java.class.path"));

更改为:

File war = new File(".");
