當我嘗試在生產環境上運行時，方法processOverridesBelongsTo上的ActiveJDBC Nullpointer異常

Question

我使用IntelliJ idea Ultimate 2018.2，我正在正常運行我的maven javafx桌面應用程序，但是當我編譯jar（帶有ant）以用於生產時，我在儀器部分得到了這個：

這是我關於ANT的工具：

<java classname="org.javalite.instrumentation.Main">
          <sysproperty key="outputDirectory" value="${ventas.output.dir}"/>
          <classpath refid="ventas.module.classpath"/>
</java>

它停止檢測，但是我直接在JAR上復制了檢測的類。 當我嘗試運行JAR時，我得到了：

我使用Java 10，嘗試使用Java 9，但同樣，Java 8與其他項目庫不兼容。 使用activeJDBC 2.2

有人可以告訴我我做錯了什么還是應該執行JAR怎么辦？

Answer 1

首先，您需要發布ventas.module.classpath的內容。 其次，ActiveJDBC v 2.2 支持Java版本8 。

如果由於其他原因而無法降級到Java 8，則至少需要通過刪除其他依賴項來進行嘗試，然后嘗試在Java 8上復制此問題。ActiveJDBC確實在Java 9上非正式運行，因此，也許您還有另一個問題與您如何上課。

另外，如果您在項目中使用Maven，為什么不同時使用它進行檢測呢？ 請參閱： http ： //javalite.io/instrumentation#maven-instrumentation-plugin

另外，您說“ 儀器停止 ”-尚不清楚是完成儀器還是在中間停止？ 手動構建jar文件時，請不要忘記包含在檢測過程中生成的文件activejdbc_models.properties 。
