自定義Maven Checkstyle插件

Question

我正在嘗試創建自定義樣式。 SNAPSHOT已經在聲吶類型上使用了，但是我嘗試對其進行測試的測試項目無法實現依賴。 錯誤是

這是項目pom

知道為什么不下載依賴插件嗎？

Answer 1

解決方法很簡單。 因為我要獲取的是插件，所以我需要使用pluginRepositories而不是repositories

  <pluginRepositories>
    <pluginRepository>
      <id>sonatype-nexus-snapshots</id>
      <name>Sonatype Nexus Snapshots</name>
      <url>https://oss.sonatype.org/content/repositories/snapshots</url>
      <releases>
        <enabled>false</enabled>
      </releases>
      <snapshots>
        <enabled>true</enabled>
      </snapshots>
    </pluginRepository>
  </pluginRepositories>

Answer 2

您可以看到maven正在錯誤的倉庫中尋找快照http://repository.apache.org/snapshots/
您的工件在https://oss.sonatype.org/content/repositories/snapshots

您用來運行的pom不是定義sonatype <repository>的pom，或者它正在被覆蓋。 檢查運行maven的文件夾中的有效pom並找到定義，您可能會發現它是apache.org而不是sonatype的

另外，通常不建議在pom中使用<repository> ，因為它會使工件無法被無法訪問特殊<repository>的其他人使用，請查看本文 。 我更喜歡在settings.xml中配置自定義存儲庫（sonatype快照）
