Maven錯誤：無法執行目標org.codehaus.mojo：exec-maven-plugin：1.2.1：exec

Question

我正在使用netbeans。 我試圖重新安裝它，但是沒有用。 以下是我運行mvn clean install -X時的堆棧跟蹤：

我也嘗試重新安裝maiven並刪除我的本地存儲庫。 如果您能幫助我，我將不勝感激。

通過在我的NetBeans項目上將exec-maven-plugin 1.2.1升級到1.6.0來解決。

您可以通過以下方式執行此操作：

Project > Properties > Actions

在那里，選擇運行proyect並將“ org.codehaus.mojo：exec-maven-plugin：1.2.1：exec”替換為“ org.codehaus.mojo：exec-maven-plugin：1.6.0：exec”。
