無法運行jar文件獲取「錯誤：無法找到或加載主類com.trident.SchedulerMain」

Question

我知道這是this等重複問題。但在嘗試了所有解決方案之後，我仍然面臨着這個問題。

這是我的pom.xml。

而且mvn的版本是：

Apache Maven 3.3.9 Maven home: /usr/share/maven Java version: 1.8.0_144, vendor: Oracle Corporation Java home: /usr/lib/jvm/java-8-oracle/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "4.10.0-32-generic", arch: "amd64", family: "unix"

，我使用下面的命令來運行jar文件

• java -jar xyz.jar 並得到錯誤：no main manifest attribute, in xyz.jar
• java -cp xyz.jar com.trident.SchedulerMain並得到錯誤： Error: Could not find or load main class com.trident.SchedulerMain

即使嘗試創建MANIFEST.MF並添加這些行

Main-Class: com.trident.SchedulerMain

但仍沒有運氣。任何人都可以幫助我嗎？

Answer 1

請確保您將.class文件的位置添加到類路徑中。如果你的.class文件在當前文件夾中，然後添加。到你的類路徑。如果你的班級在一個包中，那麼請致電java -classpath . packagename.ClassName
