Maven Spring Boot 编译失败

标签 maven spring-boot heroku

我正在尝试使用 maven 构建 spring-boot 2.0.0.RELEASE 应用程序，该应用程序将部署到 Heroku。 我正在使用 IntelliJ 进行开发，但是 maven 使用命令 mvn spring-boot:run/mvc clean install 给出编译错误。

我的pom.xml

我还使用 Kotlin 处理数据类，使用 Java 处理其他类。 这是我第一次使用 maven 构建，所以我无法解决这个问题。

该项目可通过 github 获取

最佳答案

在编译 Kotlin 代码之前，先编译 Java 代码。导致依赖Kotlin代码的Java代码无法编译。

解决方案是 described in Kotlin's documentation 。您需要更新您的 pom，以便通过禁用默认的 Java 编译目标，在 Java 编译之前执行 Kotlin 编译:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <executions>
                <!-- Replacing default-compile as it is treated specially by maven -->
                <execution>
                    <id>default-compile</id>
                    <phase>none</phase>
                </execution>
                <!-- Replacing default-testCompile as it is treated specially by maven -->
                <execution>
                    <id>default-testCompile</id>
                    <phase>none</phase>
                </execution>
                <execution>
                    <id>java-compile</id>
                    <phase>compile</phase>
