我想尝试新的东西并使用Dagger 2作为我的DI框架。所以我有以下pom和"你好世界"咖啡机类(http://google.github.io/dagger/)在我的项目中。
但是当我进行mvn clean安装时,不会生成任何类。据我所知,应该有一个" Dagger_CoffeeShop"类生成。嗯......我错过了什么?

对于那些使用Gradle的人:确保引用Dagger依赖关系如下:
compile 'com.google.dagger:dagger:2.0.2'
apt 'com.google.dagger:dagger-compiler:2.0.2'
如果您遇到apt
不支持,请添加
1)进入模块app\build.gradle
:
apply plugin: 'com.neenbedankt.android-apt'
2)进入项目\build.gradle
:
buildscript {
dependencies {
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}

我遇到了同样的问题,只有发布版本2.0。
在我的情况下,以下两个步骤解决了这个问题:
target/generated-sources/annotations
添加到我的构建路径将<forceJavacCompilerUse>true</forceJavacCompilerUse>
添加到maven编译器插件
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<dependencies>
<dependency>
<groupId>com.google.dagger</groupId>
<artifactId>dagger-compiler</artifactId>
<version>2.0</version>
</dependency>
</dependencies>
<configuration>
<source>1.8</source>
<target>1.8</target>
<!-- workaround for http://jira.codehaus.org/browse/MCOMPILER-202 -->
<forceJavacCompilerUse>true</forceJavacCompilerUse>
</configuration>
</plugin>

这不是最好的答案。当我使用下载的JAR文件(在下面的POM文件中注释掉)时,我也没有生成Dagger_文件。一旦我将存储库添加到POM,一切正常。
