                        `-- Application

当我运行mvn clean install -P集成时,我收到消息：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:testCompile (default-testCompile) on project mp-schedule-integration-test: Compilation failure: Compilation failure:
[ERROR] /Users/me/dev/my-module/my-module-integration-test/src/test/java/my/module/ws/rest/MyTest.java:[3,28] cannot find symbol
[ERROR] symbol:   class Application
[ERROR] location: package my.module

如果我将Application类放在my-module-integration-test中的测试结构中,它可以工作(Go Horse)

有人能帮助我吗？

Ps：名称os模块和项目可能是错误的只是为了隐藏原始名称.

解决方法

– github发布后更新

问题是在mp-schedule-ws模块的pom.xml中调用的重新打包spring-boot-maven-plugin.一旦spring-boot-maven-plugin包含在你的pom.xml中,它就会自动尝试重写档案,使用spring-boot：repackage目标使它们可执行.

由于mp-integration-test包中的依赖性,mp-schedule-ws / target / mp-schedule-ws-1.0-SNAPSHOT.jar实际上将在类路径上,但如果你看一下内部,你会看到它加载org / springframework / boot / loader / *类,并且您的类将驻留在BOOT-INF文件夹中,例如BOOT-INF / classes / com / cnova / mpschedule / Application.class.

If you put the spring-boot-maven-plugin in comment,your build works like a
charm.

要解决此问题,您可以遵循以下策略：

>使用classifier为重新打包的可执行文件构建一个单独的jar
>有条件地将spring-boot-maven-plugin构建执行绑定到特定的打包配置文件,以便它不会在集成测试配置文件中执行
>创建一个单独的模块,仅用于构建spring boot可执行jar
> spring boot插件使用.jar.original扩展名保留原始jar的备份,您可以使用maven插件复制它并将其添加到类路径[丑陋的黑客]

通过在mp-schedule-ws的pom.xml中添加分类器的第一个策略示例：

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <executable>true</executable>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                    <configuration>
                        <classifier>exec</classifier>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

这将给你2个罐子：

$ls -al mp-schedule-ws/target/
-rwxr--r--  1 nick  wheel  55188756 Nov 23 06:38 mp-schedule-ws-1.0-SNAPSHOT-exec.jar
-rw-r--r--  1 nick  wheel     20311 Nov 23 06:38 mp-schedule-ws-1.0-SNAPSHOT.jar

第二个策略的另一个示例是在mp-schedule-ws模块中定义特定的构建配置文件,例如：

<profiles>
    <profile>
        <id>package-application</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        <executable>true</executable>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

这给出了：

$apache-maven-3.3.9/bin/mvn clean install -P integration

[INFO] mp-schedule ........................................ SUCCESS [  0.230 s]
[INFO] mp-schedule-core ................................... SUCCESS [  3.845 s]
[INFO] mp-schedule-ws ..................................... SUCCESS [  0.563 s]
[INFO] mp-schedule-integration-test ....................... SUCCESS [  0.721 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 5.751 s

并为Spring Boot构建可执行jar：

$apache-maven-3.3.9/bin/mvn clean install -P package-application

[INFO] mp-schedule ........................................ SUCCESS [  0.255 s]
[INFO] mp-schedule-core ................................... SUCCESS [  3.822 s]
[INFO] mp-schedule-ws ..................................... SUCCESS [  0.968 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 5.396 s

当然,您可以选择最适合您项目的解决方案策略.

– 旧答案 – 过时,保留供参考

它在maven 3.x上工作,我唯一需要改变的是添加

<version>1.0-SNAPSHOT</version>

因为你在my.artifact.integration.test中声明了依赖项,所以my.artifact.ws

<dependency>
    <groupId>my.group</groupId>
    <artifactId>my.artifact.ws</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

我还添加了一个缺少的< properties>在本地配置文件中启动标记.
