在 netbeans 中编译期间出现 Maven 错误

Question

当我在 netbeans 中执行我的第一个 java 应用程序时，我被要求安装与 maven 相关的东西，但安装自己失败了。

"Run project (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.

??????? ?????? ?????????? ???????:

"Clean and build (SHIFT + F11)"成功！！！
（为什么 "Run project (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

我尝试了一切并安装了很多东西，还使用 synaptic 重新安装了所有 maven 包。下次我尝试时 - 它工作正常。
