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>

当我运行此配置时,我不断收到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

    ...

当我检查这些工件的依赖关系时,com.google.auto.value:auto-value:1.6.5在检查父母之后)依赖于com.squareup:javapoet:1.9.0,并且com.google.dagger:dagger-compiler:2.24依赖于com.squareup:javapoet:1.11.1.

当我检查in的签名ClassName::withoutAnnotationcom:squareup:javapoet:1.11.1public ClassName withoutAnnotations()

in签名ClassName::withoutAnnotationcom:squareup:javapoet:1.9.0public TypeName withoutAnnotations()

因此,确实存在冲突。

如果它是正常的依赖项,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.

那么我该如何解决这种冲突annotationProcessorPaths呢?

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>

(我们为同样的问题了同样的事情。)

此外,我已经启动了更新 AutoValue 的过程,以避免(目前)这个问题。到目前为止,这只是这个 commit

(另外,一个技术说明:冲突并不像最初看起来那么糟糕:withoutAnnotations返回的版本TypeName存在于两个版本的字节码中。这是因为,在 1.10.0+ 中,编译器会自动在除了返回的“真实”版本ClassName。我立即完全理解了这一点,根本没有提交错误的错误报告;))
