Maven 編譯時出錯 netbeans

Question

當我在 netbeans 中執行我的第一個 java 應用程序時，我被要求安裝與 maven 相關的東西，安裝失敗。

“運行項目（F6）”：

cd /home/sagecat/Documents/Study/Cross-platform_programming_tools/working_directory/Lab2/Lab2; JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 /opt/netbeans/java/maven/bin/mvn "-Dexec.args=-classpath %classpath edu.sora.lab2.Lab2_Pavlenko_KI33" -Dexec.executable=/usr/lib/jvm/java-11-openjdk-amd64/bin/java -Dfile.encoding=UTF-8 org.codehaus.mojo:exec-maven-plugin:1.5.0:exec
Running NetBeans Compile On Save execution. Phase execution is skipped and output directories of dependency projects (with Compile on Save turned on) will be used instead of their jar artifacts.

“清理並構建（SHIFT + F11）”成功！！！
（為什么“運行項目（F6）”效果不好？？？我很困惑）：

cd /home/sagecat/Documents/Study/Cross-platform_programming_tools/working_directory/Lab2/Lab2; JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 /opt/netbeans/java/maven/bin/mvn -Dfile.encoding=UTF-8 clean install

也許有用的信息：

“maven”搜索的可用插件：

已安裝的插件：

java* 類別中的所有可用插件：

Answer 1

您需要在 netbeans 中安裝 maven 插件。 這樣做 go 到工具 - >插件。 在可用插件部分，Select Maven 插件用於 JAVA。 安裝它並且必須激活它。 這個插件是必須的

如果這在可用插件列表中不可用，請檢查其他選項卡

Answer 2

解決了！

我不知道實際上有什么幫助...對不起=（

我嘗試了一切並安裝了很多東西，還使用突觸重新安裝了所有 maven 軟件包。 下次我嘗試時-效果很好。
