我有一个类似的问题，并尝试了建议的解决方案（两次执行 maven-compiler-plugin，第一次使用proc:none和第二次使用proc:only）但遇到了以下问题：
1）运行mvn clean install：在运行注释处理器之前，两个执行（proc:none和proc:only）都将编译源代码并生成类文件：
[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ foo ---
[INFO] Changes detected - recompiling the module!
[INFO] Compiling 6 source files to <mumble>\foo\target\classes
[INFO]
[INFO] --- maven-compiler-plugin:3.1:compile (process-annotations) @ foo ---
[INFO] Changes detected - recompiling the module!
[INFO] Compiling 6 source files to <mumble>\foo\target\classes
[MyAnnotationProcessor] processing ...
2)mvn install在上一次安装之后运行：两次执行 (proc:none和proc:only) 都确定类文件是最新的并且什么都不做，并且注释处理器没有运行：
[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ foo ---
[INFO] Nothing to compile - all classes are up to date
[INFO]
[INFO] --- maven-compiler-plugin:3.1:compile (process-annotations) @ foo ---
[INFO] Nothing to compile - all classes are up to date
所以在第一种情况下，java 文件被编译了两次（我的一个模块有数千个文件，这会显着影响构建时间）。而在第二种情况下，什么也没有发生，因为类文件已经存在。这是使用版本 3.1 和 3.0 的maven-compiler-plugin.
对于maven-compiler-plugin2.5.1 版本，第二次执行 ( proc:only) 将始终确定类文件是最新的并且不运行注释处理器，无论我是在运行mvn clean install还是mvn install，所以第二次执行是没有意义的。
插件配置如下：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
<executions>
<execution>
<id>default-compile</id>
<configuration>
<proc>none</proc>
</configuration>
</execution>
<execution>
<id>process-annotations</id>
<goals><goal>compile</goal></goals>
<configuration>
<proc>only</proc>
<annotationProcessors>
<annotationProcessor>MyAnnotationProcessor</annotationProcessor>
</annotationProcessors>
</configuration>
</execution>
</plugin>
所以proc:onlyoption 似乎在 3.0 和 3.1 版本中编译源代码（使其与 相同proc:both，这会影响性能）或在 2.5.1 版本中不采取任何操作（使其与 相同proc:none，这会影响功能）。
不知道如何解决这个问题......

即使proc:only在编译器选项中有一个[parsing started RegularFileObject]条目......也许它只是记录它但实际上加载了类文件？
