执行Maven JLink时获取NullPointerException

问题描述

我在pom.xml中添加的以下插件

            <plugin>
                <groupId>org.openjfx</groupId>
                <artifactId>javafx-maven-plugin</artifactId>
                <version>${javafx.plugin.version}</version>
                <configuration>
                    <stripDebug>true</stripDebug>
                    <compress>2</compress>
                    <noHeaderFiles>true</noHeaderFiles>
                    <noManPages>true</noManPages>
                    <launcher>testapp</launcher>
                    <jlinkImageName>testapp</jlinkImageName>
                    <jlinkZipName>testapp-zip</jlinkZipName>
                    <mainClass>com.testapp.Application</mainClass>
                </configuration>
            </plugin>

以下是运行maven命令时的堆栈跟踪：mvn clean javafx:jlink -X
