如何在Intellij IDEA中設置Maven項目12

Question

我有問題將NetBeans創建的Maven項目導入到IDEA 12中。在POM中編寫的依賴項工件不起作用。它告訴我「無法解析」import org.springframework.xxx;「上的符號'springframework'」。「當我運行它時，它說org.springframework.xxx不存在。 這裏是POM文件

Answer 1

如果該項目在命令行（mvn clean install）的機會就像是100％它會在12的IntelliJ工作太:-)

文件後上運行 - >項目導入 - >從外部Maven模型你應該看到模塊。

我在IntelliJ設置中檢查的是Maven主目錄（文件 - >設置 - > Maven）和它讀取（或不讀取）的settings.xml文件的位置。

IDE中的mvn install應該與命令行中發生的不同。如果是這樣，它會比較從命令行和IntelliJ（也可能來自Netbeans）的輸出mvn help:effective-settings。

如果你只是看不到所有模塊，請右鍵單擊parent-pom.xml並選擇maven - > reimport。要解決依賴關係，您必須執行一次安裝。它不會自動解決所有情況下的依賴關係。

Answer 2

更新版本神器org.jboss.spec：的jboss-的JavaEE 6.0高達3.0.1.Final-的redhat-1

<dependency> 
    <groupId>org.jboss.spec</groupId> 
    <artifactId>jboss-javaee-6.0</artifactId> 
    <version>3.0.1.Final-redhat-1</version> 
    <type>pom</type> 
    <scope>provided</scope>  
</dependency> 

Answer 3

有同樣的問題， 可以只需右鍵單擊代碼並轉到Maven-> Reimport，它應該可以做到這一點

Answer 4

我使用mvn -U idea:idea來生成下載了依賴關係的IntelliJ特定文件。

Answer 5

當pom.xml文件在你的項目中可用，您可以通過運行此命令生成的IntelliJ IDEA的項目所需要的文件：

mvn idea:idea
