Question

尝试安装组件时收到以下错误。

令人感到奇怪的是，原因似乎是：Caused by: java.lang.NoClassDefFoundError: javá/nio/fiìe/FileStore用这些口音写成。 java -version和javac -version都返回版本7，因此FileStore类应该存在，但是在没有这些重音的包中。我删除了所有~/m2但没有成功。从日志中可以看出，使用了jar插件的2.3.2版本;此插件的pom.xml未设置任何配置，仅artifactId，groupId和version。

根据带有-X的Maven堆栈跟踪的第一部分，语言环境是en_US，编码是UTF-8：

Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.7.0_40, vendor: Oracle Corporation
Java home: /x/s/jdk1.7.0_40/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.2.0-54-generic", arch: "amd64", family: "unix"

使用-X调用时，跟踪的最后一部分是：

Answer 1

您的内存有缺陷或硬盘上的某个JAR损坏了。

删除/home/dev/.m2/repository然后重试。

如果这不能解决问题，请运行内存测试。如果显示某些内容，则修复PC。如果没有显示任何内容，请更换PC - 内存测试并不总能找到缺陷。如果他们找到了什么，你可以确定存在问题。如果他们什么也没找到，你根本就不知道，因为某种访问模式可能会导致问题。

Answer 2

首先尝试确保JDK安装本身没有问题。如果编译/运行失败，则重新安装JDK。

import java.io.*;
import java.nio.file.*;
class Scratch {
    public static void main(String[] args) throws IOException {
        FileStore fs = Files.getFileStore(Paths.get(".", "."));
        System.out.println(fs);
    }
}
