我有一个使用Dagger2并使用Maven构建的桌面Java项目。我无法顺序运行compile和package。这工作：Maven：编译OK，包OK，编译+包失败
$ mvn clean
$ mvn compile
而这个工作，产生无差错运行一个可执行的JAR：
$ mvn clean
$ mvn package
但这种失败：
$ mvn clean
$ mvn compile
$ mvn package
当package到达使用Dagger2模块它输出：
[INFO] Changes detected - recompiling the module!
从mvn -e package错误是：

该模块具有这种依赖性：
<dependency>
<groupId>com.google.dagger</groupId>
<artifactId>dagger</artifactId>
<version>2.1</version>
<scope>compile</scope>
</dependency>
该模块使用编译器插件版本3.3这样的：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<dependencies>
<dependency>
<groupId>com.google.dagger</groupId>
<artifactId>dagger-compiler</artifactId>
<version>2.1</version>
</dependency>
</dependencies>
<configuration>
<source>1.7</source>
<target>1.7</target>
<forceJavacCompilerUse>true</forceJavacCompilerUse>
</configuration>
</plugin>
这是唯一的匕首相关的配置。为什么我不能在build之后运行package？
可能相关：我认为forceJavacCompilerUse不再需要，但没有它，匕首似乎根本没有运行。生成的组件实现（DaggerMyComponent）上出现未知符号错误。
编辑：这是mvn -e package全力输出，命令提示符命令提示符：

编辑2：我注意到，当我clean后通过自身运行package，它说，它的编译6个来源。这是项目中有多少手写课程。当我在package之前运行compile时，后者说它正在编译8个源文件。它看起来像是在一个干净的项目上运行dagger-compiler时，它会静静地生成并编译它的源代码。然后package看到新的来源，并试图编译它们。神秘的是它失败的原因。连续两次运行compile以同样的方式失败。
编辑3：我试图this answer，指定dagger.internal.codegen.ComponentProcessor作为-processor参数。现在，我第一次运行编译，我看到它编译6个文件的两个通道，然后8个文件：
[INFO] --- maven-compiler-plugin:3.3:compile (process-annotations) @ weapon ---

这是预期，而这compile成功。但是，如果我再次运行package或compile，则它会像以前一样失败。
匕首生产的来源在/target/generated-sources/annotations。我想我需要告诉Maven做这件事情，但我不知道该怎么做。 compile在连续运行两次时会检测到源变化，但我不知道为什么会导致失败。也许我需要有条件地运行注释处理步骤，但我不知道该怎么做或条件应该如何。
你可以根据编译错误消息显示完整的错误输出原因，必须有更多的输出... – khmarbaise
@khmarbaise这是完整的输出。我唯一遗漏的是最后的“更多信息...”样板。 –
不是。在maven-compiler-plugin附近有输出，它显示了真正的问题，不仅仅是最后的部分... – khmarbaise
