Spring Boot和Maven Shade插件问题

Question

im试图在我的spring boot多模块项目中运行以下测试，并注意到maven shade插件避免spring查找依赖项。我注意到删除了以下工作，但是，这将导致应用程序启动失败，因为找不到主类。

<transformer
                                                implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                            <manifestEntries>
                                                <Main-Class>${application.mainClass}</Main-Class>
                                            </manifestEntries>
                                        </transformer>

下面是我的测试

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
class AcceptanceBase extends Specification {

    // Wiremock
    protected static WireMockServer wireMockServer = new WireMockServer(
            options().port(8081).
                    usingFilesUnderDirectory("src/test/resources/wiremock").
                    notifier(new ConsoleNotifier(true)))

    // Rest assured<
    protected static RequestSpecification apiRequestSpec

    def setupSpec() {
        initSpec()
        wireMockServer.start()
    }

    def cleanupSpec() {
        wireMockServer.stop()
    }

    def initSpec() {
        apiRequestSpec = new RequestSpecBuilder()
                .addHeader("X-ApiKey", "5512c8d59932b3da984cc7de")
                .setContentType(ContentType.JSON)
                .setBaseUri("http://localhost:8086/api/flights/itineraries/composition")
                .build()
    }
}

使用maven配置

                        <artifactId>maven-shade-plugin</artifactId>

我想了解为什么会发生这种情况以及是否有解决方法。弹簧启动多模块布局可能存在问题，因为应用程序类不在主项目中，而在内部模块中。

-> api-interfaces
-> api-application
-> api-services (Application.class is situated here)
