mvn依賴關係中的結果不正確：analyze

我一直在尋找一種工具，它能夠向您顯示未使用的依賴關係。我很快就發現了maven命令mvn dependency:analyze。與此相關的問題是，它經常檢測到「未使用」的依賴關係，如果失敗，它會使構建失敗。mvn依賴關係中的結果不正確：analyze

下面是從一個優化的項目的示例：

$ mvn dependency:analyze

龍目的使用包是：

lombok.Getter 
lombok.Setter

通過從卸下Lombok的我的POM我通過Buildig項目獲得以下錯誤

而且沒有log4j的，演員我得到運行項目

log4j:ERROR Could not instantiate class [org.apache.log4j.rolling.RollingFileAppender]. 
java.lang.ClassNotFoundException: org.apache.log4j.rolling.RollingFileAppender

兩個Log4j和龍目以下的錯誤在我的項目中使用。你有一個想法如何解決這個問題或從哪裏來？

預先感謝您

第一件事就是使用[maven-dependency-plugin]的最新版本（https://maven.apache.org/plugins/maven-dependency-plugin/）。此外，問題是如何使用這些依賴關係？ – khmarbaise

我相信分析器在字節碼級別運行，因此它可能不會檢測到像lombok已被編譯的未使用的內容。 –

您是否嘗試修改範圍？ log4j-extras可以是運行時依賴項嗎？不熟悉lombok以及如何解決這個問題 –

我也已經運行到哪裏龍目島項目已打上了dependency:analyze與未用聲明的依賴性問題。 Lombok項目大部分時間都是在編譯時進行的，因此編譯後大部分註釋都會被刪除。這就是Maven的依賴分析器無法識別它的原因。爲什麼它也無法檢測到使用SPI加載的依賴關係。

我們通過明確告訴Dependency analyzer插件忽略Project Lombok來解決此問題。這可以通過<usedDependency>配置選項來完成，或更細粒度<ignoreUnusedDeclaredDependency>這樣：

<pluginManagement> 
    <plugins> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-dependency-plugin</artifactId> 
      <version>3.0.2</version> 
      <configuration> 
       <ignoredUnusedDeclaredDependencies> 
        <ignoredUnusedDeclaredDependency>org.projectlombok:lombok</ignoredUnusedDeclaredDependency> 
       </ignoredUnusedDeclaredDependencies> 
      </configuration> 
     </plugin> 
    </plugins> 
</pluginManagement>

關於範圍PS：龍目島是一個編譯時的依賴，但不必在運行時類路徑（或結束在你的lib文件夾中）。 provided依賴關係指出該jar應該用於編譯，但在運行時它應該由運行時環境提供（例如運行它的容器）。由於在運行時不需要Lombok，因此當您的運行時不提供Lombok時，不會出現任何問題，這與Maven依賴聲明期望的相反。
