Question

我们刚刚将JBoss从6.1.0升级到Wildfly 10.1，并对模块和工件版本进行了各种相关的升级，等等。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IllegalStateException in Hibernate metamodel generation with maven并升级到maven-compiler-plugin 3.6.0（从3.1开始）。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，但结果却引发了一个新问题。

该模块的一些注释生成的源由另一个模块使用，并且找不到类文件。改变了什么？ generated-sources目录包含java文件，但是这些类没有编译。

它考虑了一点，例如将构建辅助阶段更改为来自流程源的生成源有帮助，但随后失败了。

由于3.1和3.6.0之间的变化，是否还需要更改其他内容？（我不熟悉如何处理注释 - 我只是Cobertura的支持人员。）

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。目前，没有任何生成的源被编译。使用3.1插件我必须拥有它，但是使用3.6.0我不能。

我还尝试通过使compilerArg特定于默认编译阶段来实现答案https://stackoverflow.com/a/35045416/4756238，但是没有编译生成的源。如果我没有重用default-compile id，那么构建工作并给了我生成的类文件，但它运行了两个编译阶段，-proc:none一秒，这似乎是多余的。

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>

maven-compiler-plugin 3.6.0不会从注释
