java - Maven Build 未创建可执行 jar 文件

Question

我正在尝试创建我的 Maven 项目的可执行 jar 文件。

这是我的 POM.XML

<project xmlns="http://maven.apache.org/POM/4.0.0"

                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
    <dependencies>
        <!-- https://mvnrepository.com/artifact/com.itextpdf/itextpdf -->
        <dependency>
            <groupId>com.itextpdf</groupId>
            <artifactId>itextpdf</artifactId>
            <version>5.0.6</version>
        </dependency>

    </dependencies>
</project>

这是我迄今为止尝试过的命令，但没有成功。

mvn clean compile assembly:single
mvn clean compile assembly:assembly
mvn -e -cpu,--check clean compile assembly:assembly
mvn -e -cpu,--check clean compile assembly:single
mvn clean compile assembly:single -U

这是最后一个命令的控制台输出。

Answer 1

尝试更改插件版本。根据mvn存储库( https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-assembly-plugin )，不存在版本3.7的jar
