java – 使用kotlin-maven-plugin进行注释处理

2019年7月28日 286次阅读

所以我有2个模块的maven项目.

Root pom.xml看起来像这样：

<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>

<groupId>kashier</groupId>
<artifactId>Kashier</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>

<modules>
    <module>AnnotationProcessing</module>
    <module>TestProject</module>
</modules>

和AnnotationProcessing模块的pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>

            <version>${kotlin.version}</version>
            <executions>
                <execution>
                    <id>compile</id>
                    <phase>compile</phase>
                    <goals>
                        <goal>compile</goal>
                    </goals>
                </execution>
                <execution>
                    <id>test-compile</id>
                    <phase>test-compile</phase>
                    <goals>
                        <goal>test-compile</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

现在一切正常,只有我手动创建资源目录中的javax.annotation.processing.Processor文件.
这意味着自动服务不起作用,问题是：我如何使其工作？

此外,我试图用java制作相同的项目,它的工作原理.所以我认为问题出在kotlin-maven-plugin中.

该项目的源代码可以找到here

最佳答案 自动服务也使用注释处理器,所以你必须添加到你的kotlin-maven-plugin(编译部分之前)：

<execution>
    <id>kapt</id>
    <goals>
        <goal>kapt</goal>
    </goals>
    <configuration>
        <sourceDirs>
            <sourceDir>src/main/kotlin</sourceDir>
            <sourceDir>src/main/java</sourceDir>
        </sourceDirs>
        <annotationProcessorPaths>
            <!-- Specify your annotation processors here. -->
            <annotationProcessorPath>
                <groupId>com.google.auto.service</groupId>
                <artifactId>auto-service</artifactId>
                <version>1.0-rc4</version>
            </annotationProcessorPath>
        </annotationProcessorPaths>
    </configuration>
</execution>
