沒有在當前項目和插件組中找到前綴'exec'的插件org.codehaus.mojo

Question

我已閱讀了幾個類似問題和幫助1頁面的問題。不幸的是，我被卡住了。

一個可能的原因可能是由代理引起的，但這裏沒有這樣的代理。此外，當我從Eclipse更新它時，我的PC中的所有Maven項目都已成功更新。所以我放棄了這種可能性。

我檢查的其他事情是在我的本地存儲庫中查找codehaus，並找到它（C：\ Users \ myUser.m2 \ repository \ org \ codehaus \ mojo）。

另一個嘗試，我試着在設置中添加pluginGroups/pluginGroup。 該項目是一個非常簡單的問候單詞，只使用一個Tasklet及其執行方法使用Spring批處理。沒有公共的靜態void main方法。

COMMAND.EXE與後我添加利瑪建議印刷整個錯誤：

Answer 1

您應該配置您的POM文件至少聲明Exec Maven Plugin如下：

<build> 
    <plugins> 
     <plugin> 
      <groupId>org.codehaus.mojo</groupId> 
      <artifactId>exec-maven-plugin</artifactId> 
      <version>1.1</version> 
     </plugin> 
    </plugins> 
</build> 

這樣，你就可以使用exec:java plugin：goal命令。

---

你甚至可以避開選擇：

-Dexec.mainClass=org.springframework.batch.core.launch.support.CommandLineJobRunner -Dexec.args="com.test.config.HelloWorldJobConfig helloWorldJob" 

通過在你的POM中配置它們作爲同一插件配置的一部分如下：

<plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>exec-maven-plugin</artifactId> 
    <version>1.1</version> 
    <configuration> 
     <mainClass>org.springframework.batch.core.launch.support.CommandLineJobRunner</mainClass> 
     <arguments> 
      <argument>com.test.config.HelloWorldJobConfig</argument> 
      <argument>helloWorldJob</argument> 
     </arguments> 
    </configuration> 
</plugin> 

正如你所看到的，我們實際上是在說插件在哪裏可以找到主類和它的參數。您可以簡單地調用：

mvn compile exec:java 

它應該執行相同的預期結果。

---

UPDATE1
事實上，你的Maven執行遇到問題時嘗試訪問網絡上的插件元數據：

[警告]無法檢索插件描述符org.codehaus.mojo： exec-maven- 插件：1.1：插件org.codehaus.mojo：exec-maven-plugin：1。1或它的一個依賴無法解析：無法讀取工件描述符org.codehaus .mojo：EXEC-Maven的插件：罐子：1.1

---

UPDATE2
如果你保持在插件前綴有問題時，確實可能取決於您的網絡設置。

mvn compile mvn org.codehaus.mojo:exec-maven-plugin:1.1:java 

注模式：快速檢查可以通過通過不是它的插件前綴（exec），但通過全限定名調用Exec的Maven插件如下進行，我們正在調用的Maven，那麼的groupId：artifactId的：版本：目標，它將完全相同。這將檢查你的pom配置（和插件配置）是否正確。

---

UPDATE3
作爲你的輸出日誌看出，Maven是試圖通過https訪問存儲庫（注意最後的「S」），通過SSL因此，然後有與證書問題作爲構建的一部分輸出：

sun .security.validator.ValidatorException：PKIX路徑構建失敗：sun.security。 provider.certpath.SunCertPathBuilderException：無法找到請求的目標有效的專業認證 N通路

你有那麼兩個選項：

• 泰爾行家忽略SSL錯誤，在另一個SO answer
描述
• 首先通過運行mvn help:effective-settings來檢查您的設置，以確保獲得maven應用的真實設置（如果該命令實際可用），然後在您的設置中重新配置非SSL存儲庫，並使用另一個替代SO answer
