排除 AnnotationProcessorPaths 中的依赖项

Exclude dependencies in AnnotationProcessorPaths

我有以下构建配置:

父 POM:

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.8.1</version>
      <configuration>
        <release>11</release>
        <annotationProcessorPaths>
          <path>
            <groupId>com.google.auto.value</groupId>
            <artifactId>auto-value</artifactId>
            <version>1.6.5</version>
          </path>
        </annotationProcessorPaths>
      </configuration>
    </plugin>
  </plugins>
</build>

其中一个子项目包含以下内容:

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
        <annotationProcessorPaths>
          <path>
            <groupId>com.google.dagger</groupId>
            <artifactId>dagger-compiler</artifactId>
            <version>2.24</version>
          </path>
        </annotationProcessorPaths>
      </configuration>
    </plugin>
  </plugins>
</build>

当我 运行 这个配置时,我不断得到一个 org.apache.maven.lifecycle.LifecycleExecutionException:

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project imgn: Fatal error compiling
...

    at dagger.internal.codegen.InjectBindingRegistryImpl$BindingsCollection.shouldGenerateBinding(InjectBindingRegistryImpl.java:134)
    ...

当我检查这些工件的依赖关系时,com.google.auto.value:auto-value:1.6.5 (after checking parents) 依赖于 com.squareup:javapoet:1.9.0,而 com.google.dagger:dagger-compiler:2.24 依赖于 com.squareup:javapoet:1.11.1

当我检查 signature of ClassName::withoutAnnotation in com:squareup:javapoet:1.11.1public ClassName withoutAnnotations()

signature of ClassName::withoutAnnotation in com:squareup:javapoet:1.9.0public TypeName withoutAnnotations()

所以确实存在冲突。

如果是正常的依赖,我会知道使用 <exclusions> 标签,但在这种情况下,如果我添加这样的标签,我会遇到以下问题:Cannot find 'exclusions' in class org.apache.maven.plugin.compiler.DependencyCoordinate.

那么如何解决 annotationProcessorPaths 中的此类冲突?

您可以通过直接将其添加为注释处理器路径来手动覆盖 JavaPoet 的版本:

<path>
  <groupId>com.squareup</groupId>
  <artifactId>javapoet</artifactId>
  <version>1.11.1</version>
</path>

(我们did exactly that同样的问题。)

另外,我已经启动了更新 AutoValue 的过程以避免(暂时)这个问题。到目前为止,这意味着 this commit.

(另外,技术说明:冲突并不像最初看起来那么糟糕:withoutAnnotations 的一个版本 returns TypeName 都存在于字节码中versions. 那是因为在1.10.0+,编译器除了returns ClassName的"real"版本,还自动生成了bridge method,我一下子就明白了,完全没有文件 a false bug report ;))
