Maven：编译OK，包OK，编译+包失败
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：
$ mvn clean
$ mvn compile
这工作，产生一个运行没有错误的可执行jar：
$ mvn clean
$ mvn package
但是这失败了：
$ mvn clean
$ mvn compile
$ mvn package
当package到达使用Dagger2的模块时，它会输出：
[INFO] Changes detected - recompiling the module!
mvn -e package的错误是：

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>
该模块使用如下编译器插件版本3.3：
<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>
这是唯一与Dagger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已不再需要，但如果没有它，Dagger似乎根本没有运行。 我在生成的组件实现（ DaggerMyComponent ）上收到未知的符号错误。
编辑：这是mvn -e package的全部输出，命令提示符为命令提示符：

编辑2 ：我注意到当我在clean后自行运行package时，它说它正在编译6个源文件。 这是项目中有多少手写课程。 当我在package之前运行compile ，后者说它正在编译8个源文件。 它看起来像dagger-compiler运行在一个干净的项目上时，它默默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。 在同一行中运行两次compile失败的方式相同。
编辑3：我试过这个答案，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，然后编译8个文件的两个过程：
[INFO] --- maven-compiler-plugin:3.3:compile (process-annotations) @ weapon ---
[INFO] Changes detected - recompiling the module!
[INFO] Compiling 6 source files to /home/kevin/Projects/IDEA/Dark Matter/weapon/target/classes
[INFO]
[INFO] --- maven-resources-plugin:2.3:resources (default-resources) @ weapon ---

[INFO] Changes detected - recompiling the module!
[INFO] Compiling 8 source files to /home/kevin/Projects/IDEA/Dark Matter/weapon/target/classes
这是预期的，并且这个compile成功。 但是，如果我运行package ，或再次compile ，它会像以前一样失败。
Dagger生成的源代码位于/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。 当连续运行两次时， compile检测到源变更是有道理的，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。
我设法重现你的问题。
关键似乎是maven-compiler-plugin:3.3
当我使用maven-compiler-plugin:3.1 ，错误不会显示。
