Java maven编译错误：文件名、目录名或卷标语法不正确

我正在编译我的

pom.xml

文件，并得到以下编译错误

Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.5.1:copy-dependencies (copy-dependencies) on project ElasticSearchUtility: Error copying artifact from C:\Users\10641516\.m2\repository\org\apache\lucene\lucene-sandbox\7.1.0\lucene-sandbox-7.1.0.jar to D:\Karthikeyan\ElasticSearch\ElasticSearch_Tesing\target\dependency-
    [ERROR] jars\lucene-sandbox-7.1.0.jar: The filename, directory name, or volume label syntax is incorrect

但是所需的.jar文件在指定的路径中可用

我在maven项目中创建了两个java文件，一个是POJO类，另一个是java主类文件。我想让我的项目成为一个可执行的jar文件，我想使用

java-jar

命令在外部运行它

请找到我的pom.xml文件

建议您需要将maven dependency插件的

outputDirectory

配置更改为：

                    <configuration>
                        <!-- exclude junit, we need runtime dependency only -->
                        <includeScope>runtime</includeScope>
                        <outputDirectory>
                            ${project.build.directory}/dependency-jars/
                        </outputDirectory>
                    </configuration>

运行时

为了消除中间的换行值。

谢谢。它修复了我的问题。现在，在执行JAR文件<代码>错误时，我会发现这个错误：找不到或加载主类ProjistJAR。Projtual.App。我的主要类包名是

com.es.utility.DocumentIndex

，所以我需要给出完整的包名而不是

ProjectJar.project.App

。。？（在我的pom.xml文件中）如果我添加

com.es.utility.DocumentIndex

am get

Error：找不到或加载主类com.es.utility.DocumentIndex

Error这听起来像是一个新问题。根据提供的信息，我们没有太多机会回答这个问题。我已经为这个错误创建了一个单独的问题-
