Question

我正在尝试使用javafx和maven构建一个带有主.jar外部依赖项的项目。该项目是使用netbeans创建的，我使用的是pom.xml文件的基本配置：

sizeof(T)

使用这种配置，我可以构建项目并且它可以工作，但依赖项是在项目中编译的，我需要依赖项位于.jar外部的文件夹中。一个名为lib。的文件夹。

在互联网上搜索我发现了这个配置：

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <mainClass>org.main.Main</mainClass>
</properties>

当我构建项目时，生成了lib文件夹并且在依赖项中，但是当应用程序在内部调用某些依赖项类时，它会引发以下异常：

                </execution>
            </executions>  
        </plugin>
    </plugins>
</build>

这些异常与codehaus plexus依赖关系有关，但是它与我放置的任何依赖关系一起发生，如果它是由我或其他人做出的依赖关系并不重要。根据我的理解，这些课程没有找到，我不知道为什么。

如何配置pom.xml以便拥有 .jar中的依赖项在外部文件夹中？

谢谢！

好吧，最后我发现了一个可能的解决方案。将此代码添加到第一个pom.xml文件中：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.6.1</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <showDeprecation>true</showDeprecation>
        <compilerArgument>-Xlint:unchecked</compilerArgument>
    </configuration>
</plugin>
<plugin>
    <groupId>com.zenjava</groupId>
    <artifactId>javafx-maven-plugin</artifactId>
    <version>8.8.3</version>
    <configuration>
        <mainClass>org.main.MainApp</mainClass>
        <verbose>true</verbose>
    </configuration>
    <executions>
        <execution>
            <id>create-jfxjar</id>
            <phase>package</phase>
            <goals>
                <goal>build-jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

我设法单独使用依赖项构建应用程序，而不会丢弃我显示的异常。

使用JavaFX和Maven在文件夹lib中构建具有外部依赖项的项目
