Intellij Idea Maven '無法重新連接' 錯誤

Question

也許你可以幫助我，當我在 Intellij Idea 13 上打開我的項目時，我遇到了一個奇怪的 apache maven 問題。當項目打開時，我在外部庫部分沒有庫。 在 diff 模塊的所有 pom.xml 文件中，我看到錯誤“無法重新連接”。

我嘗試使緩存無效/重新啟動想法，嘗試使用 Maven 重新導入，但問題仍然存在。 但是，如果我執行 mvn clean install，並部署我的項目，一切正常。 我使用 Maven 3.2.3。 和 Java 1.8。

Maven 設置：

Answer 1

我遇到了同樣的錯誤並像這樣修復它：

1. 按Ctrl+Alt+S打開設置並導航至Build、Execution、Deployment | 構建工具 | 馬文 | 輸入

2. 檢查JDK for Importer並從下拉列表中更改安裝在您機器上的 JDK 的確切版本（例如：1.8.0.250）。

執行相同操作后，它會提示驗證，然后，maven 將自動更新並運行項目。

就我而言，當項目從存儲庫導入時，我做了同樣的事情，因為機器中使用的 JDK 不同。 當我們卸載IDE和JDK並安裝IDE和不同版本的JDK時，IDE會像以前一樣自動獲取機器中可用的項目，但無法更改導入的JDK。

Answer 2

我通過將本地 Maven 3.3.9 更改為 Idea Bundle Maven3 來解決此問題。

Answer 3

在Intellij Idea 13中打開項目時，也許您可​​以幫我遇到一個奇怪的apache maven問題。當項目打開時，“外部庫”部分中沒有庫。 在diff模塊的所有pom.xml文件中，我看到錯誤“無法重新連接”。

我試圖使緩存/重新啟動想法無效，嘗試使用Maven重新導入，但是問題仍然存在。 但是，如果我執行mvn clean install，並部署我的項目，則一切正常。 我使用Maven 3.2.3。 和Java 1.8。

Answer 4

在這種情況下，單擊“重新加載所有 Maven 項目”對我有所幫助。

Answer 5

文件 -> 無效緩存

在 IntelliJ 似乎糾纏不清的情況下也可能會有所幫助。

Answer 6

我收到此錯誤，並通過以下步驟在 IntelliJ 中修復了此錯誤：

1]關閉所有正在運行的應用程序（如果有）
2]重新導入/重新加載 pom.xml（右鍵單擊 pom.xml -> 選擇 maven 選項->重新導入/重新加載項目）
3]然后按照此運行您的應用程序（即主文件）我不需要手動刪除.m2文件夾

Answer 7

我通過刪除來自~/.m2傳輸錯誤的.lastUpdated文件解決了這個問題

find ~/.m2  -name "*.lastUpdated" -exec grep -q "Could not transfer" {} \; -print -exec rm {} \;

Answer 8

我只是重新啟動這個想法，錯誤就消失了。

Answer 9

在我的例子中，我有 maven 運行器和導入器設置為使用 Project JDK，但我通過將 JDK 從 OpenJDK 更改為 Liberica JDK（相同的 Java 版本）設法解決了這個問題，它神奇地開始工作。

因此，對於有類似問題的任何人，請嘗試將 JDK 更改為不同的實現。

Answer 10

如果您在帶有X-Server （例如 VcXsrv）的WSL中運行 InteliJ，解決方案可能是

1. 關閉 InteliJ
2. 重啟服務器
3. 打開 Intelij

它會起作用的。
