This might simply be a maven question. I'm just getting started with Dagger 2 which uses javax.annotation.processing to generate sources based on annotations.

When I use my IDE, IntelliJ, and build the project (Build - Rebuild Project) it places the generated sources files (i.e. $$Factory and Dagger_) in:

target/generated-sources/annotations

IntelliJ automatically declares this as a source root so using the generated classes doesn't get marked as an error:

// Dagger_CoffeeApp$$Coffee is a generated class
Coffee coffee = Dagger_CoffeeApp$Coffee.builder().build();

The problem is that if I build from the command line via maven:

mvn clean compile

The generated sources are located in:

target/classes

And thus the files are marked with an error in my IDE. I could probably simply add target/classes as a source root, but ideally I would like compiling from the command line to be consistent with my IDE. Is there some argument to maven to specify which directory the generated sources files are generated in?

随着前缀类的生成，您应该通过将dagger-compiler的 jar配置Dagger到项目的工厂路径中来设置 eclipse 以在构建过程中生成它们

要使用 maven 自动化此过程，请参阅使用apt-maven-plugin 的这个问题

您可以尝试使用 maven-processor-plugin 为注释处理器指定特定目标，可能是这样的：

<plugin>
  <groupId>org.bsc.maven</groupId>
  <artifactId>maven-processor-plugin</artifactId>
  <version>1.0-SNAPSHOT</version>
  <executions>
    <execution>
      <id>process</id>
      <goals>
        <goal>process</goal>
      </goals>
      <phase>generate-sources</phase>
      <configuration>
        <outputDirectory>target/generated-sources/annotations</outputDirectory>
      </configuration> 
    </execution>
  </executions>
</plugin>

我还没有对此进行测试，但它可能会起作用。从这个问题中获取想法：在 Maven 中为注释处理器设置生成的源目录
