maven-compiler-plugin 3.6.0 不从注释编译生成的源

Question

我们刚刚将我们的 JBoss 从 6.1.0 升级到 Wildfly 10.1，并对模块和工件版本等进行了各种关联升级。在一个模块中，这导致我们的 cobertura 编译失败并出现编译器错误。我找到并升级到 maven-compiler-plugin 3.6.0（从 3.1）。这似乎解决了我的问题，但仅限于本地。我可以为 cobertura 编译模块，但结果导致了一个新问题。

此模块的一些注释生成的源被另一个模块使用，class 文件未找到。什么改变了？ generated-sources 目录包含 java 文件，但 classes 未编译。

它曾考虑过将 build-helper 阶段更改为从 process-sources 生成源代码这一点有所帮助，但随后失败了。

3.1 和 3.6.0 之间有什么变化需要改变吗？（我不熟悉如何处理注释 - 我只是 Cobertura 支持人员。）

Answer 1

我通过从编译器插件中删除 -proc:none 编译器参数来解决这个问题。有了这个 none 生成的源代码就被编译了。使用 3.1 插件我必须拥有它，但使用 3.6.0 我不能。

我还尝试通过使 compilerArg 特定于 default-compile 阶段来实现答案，但这并没有编译生成的源代码。如果我不重用 default-compile id，构建工作并为我生成 class 文件，但它运行两个编译阶段，-proc:none 一秒钟，这似乎多余的。

编译器的最终 pom 部分如下所示：

<plugin>
   <artifactId>maven-compiler-plugin</artifactId>
   <executions>
     <execution>
       <id>run-annotation-processors-only</id>
       <phase>generate-sources</phase>
       <configuration>
         <compilerArgument>-proc:only</compilerArgument>
       </configuration>
       <goals>
         <goal>compile</goal>
       </goals>
     </execution>
   </executions>
</plugin>
