Question

我尝试将Kotlin与Maven一起使用，所以我遵循了documentation

我在pom.xml文件中有这个配置

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <kotlin.version>1.2.10</kotlin.version>
</properties>

<build>
    <sourceDirectory>${project.basedir}/src/main/kotlin</sourceDirectory>
    <testSourceDirectory>${project.basedir}/src/test/kotlin</testSourceDirectory>
    <plugins>
        <plugin>
            <artifactId>kotlin-maven-plugin</artifactId>
            <groupId>org.jetbrains.kotlin</groupId>
            <version>${kotlin.version}</version>

            <executions>
                <execution>
                    <id>compile</id>
                    <goals>
                        <goal>compile</goal>
                    </goals>
                </execution>

                <execution>
                    <id>test-compile</id>
                    <goals>
                        <goal>test-compile</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

<dependencies>
    <dependency>
        <groupId>org.jetbrains.kotlin</groupId>
        <artifactId>kotlin-stdlib-jdk8</artifactId>
        <version>${kotlin.version}</version>
    </dependency>
    <dependency>
        <groupId>org.jetbrains.kotlin</groupId>
        <artifactId>kotlin-reflect</artifactId>
        <version>${kotlin.version}</version>
    </dependency>
</dependencies>

来源文件夹为src/main/kotlin和src/test/kotlin

当我mvn clean install时，我收到了此错误

[ERROR] Failed to execute goal org.jetbrains.kotlin:kotlin-maven-plugin:1.2.10:compile (compile) on project kotlin-starter: Execution compile of goal org.jetbrains.kotlin:kotlin-maven-plugin:1.2.10:compile failed: A required class was missing while executing org.jetbrains.kotlin:kotlin-maven-plugin:1.2.10:compile: kotlin/reflect/KDeclarationContainer
[ERROR] -----------------------------------------------------
[ERROR] realm =    plugin>org.jetbrains.kotlin:kotlin-maven-plugin:1.2.10
[ERROR] strategy = org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy
...

我也尝试使用kotlin-stdlib代替kotlin-stdlib-jdk8，但我遇到了同样的错误。当我打开库时，我在包KDeclarationContainer中看到了类kotlin.reflect，所以我不明白为什么会出现这个错误？

编辑：当我将kotlin版本更改为<kotlin.version>1.1.61</kotlin.version>时，一切正常...

我和kotlin-maven-plugin / 1.2.20有一个非常类似的问题，在我从我当地的maven repo中删除org / jetbrains并重新运行构建后，它就消失了。我只能认为某些内容已损坏或丢失。
