Java 在多模块maven项目中运行exec maven插件时出现问题

我有一个多模块Maven项目，有一个主pom和许多子目录，每个子目录都包含引用主pom的项目（和pom.xml文件）

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>

在projectA中包含对exec maven插件的调用，该插件执行java目标并成功调用驻留在projectA中某处的测试类（projectA/test/com/mycompany/Testclass.java）。插件声明如下： org.codehaus.mojo execmaven插件 1.2.1

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>

完成此操作后，我成功加载了该类，但在com.google.gson.JsonSyntaxException上获得了ClassNotFoundException

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>

这与我从命令行运行该类时遇到的错误相同，如下所示

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>

java-classpath“projectA/target/projectA-6.6.1-bSOURCE-tests.jar；projectA/target/projectA-6.6.1-bSOURCE.jar”com.mycompany.Testclass

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>

在projectB中，我想我想使用exec maven插件的java目标，而不是exec目标，但无论如何，我必须能够指定类路径

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>

你知道我该怎么做吗

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>

谢谢。

这是我自己想出来的，我正在发布我的答案，以防其他人需要它，或者有人想质疑它（或者提出更好的建议）

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>

我所做的是在下属项目projectB中添加一个依赖项，如下所示：

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>

    <dependency>
        <groupId>com.mycompany</groupId>
        <artifactId>projectA</artifactId>
        <version>6.6-SNAPSHOT</version>
        <scope>test</scope>
        <classifier>tests</classifier>
    </dependency>

com.mycompany
项目A
6.6-1
测试
测验

我相信关键是元素，它指示maven从包含projectA中测试类的jar文件中获取依赖类

                <execution>
                    <id>execute-test</id>
                    <phase>pre-integration-test</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.mycompany.Testclass</mainClass>
                        <classpathScope>test</classpathScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>
