使用maven編譯時出現編譯錯誤（未能解析工件）

我在爲一個任務做一個應用程序。我是一名初學者。我通過修改我的老師給我的一個例子來完成這項任務。我試圖通過使用maven來使用命令行編譯應用程序。發生構建錯誤。使用maven編譯時出現編譯錯誤（未能解析工件）

你好像缺少${derby-version}財產。

你應該在你的POM定義爲

<properties> 
<derby-version>YOUR_DERBY_VERSION_IDENTIFIER_HERE</derby-version> 
</properties>

謝謝。我修好了。我修改了pom文件是一個子文件。因此我錯過了父文件中的一些依賴關係。 –

從這一行很顯然，

mvn install:install-file -DgroupId=org.eclipse.persistence 
-DartifactId=eclipselink -Dversion=${derby-version} -Dpackaging=jar 
-Dfile=/path/to/file

Maven是不能夠解決在編譯時間德比版本值。

因此，要麼Raibaz建議在你的pom文件中聲明derby-version變量，要麼在所有依賴項（不推薦）中用實際值替換變量。
