我在使用maven進行註釋處理期間使用CodeModel生成代碼。該代碼是JUnit的測試:NoClassDefFoundError:註釋處理期間的org/junit/AfterClass
JMethod tearDownClass = testClass.method(
JMod.PUBLIC | JMod.STATIC, Void.class, "tearDownClass");
tearDownClass._throws(Exception.class);
tearDownClass.annotate(AfterClass.class); <- java.lang.NoClassDefFoundError
然而,編譯過程中拋出一個java.lang.NoClassDefFoundError : org/junit/AfterClass
當它試圖獲取AfterClass.class
,這是一個註釋本身。
的依賴JUnit的定義如下:
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.8.2</version>
</dependency>
所以AfterClass.class
應該在我的代碼可用。
如何解決這個問題呢?
不清楚
代碼調用codemodel是在編譯圖書館,JUnit是不是一個「測試」的依賴。但是,調用生成代碼的代碼具有相同的junit依賴性,但是作爲測試依賴性。
如果我將後者依賴項更改爲「不是測試」依賴項,則問題會消失。爲什麼我必須將此依賴性定義爲「不是測試」,儘管只有庫調用codemodel明確地使用它?

你知道問題是junit類在類路徑中不可用嗎? –
@Thorbjorn是的,但仍然令人困惑(請參閱我的問題中的更新) – JVerstry
您是否檢查過此項目的依賴關係樹?運行mvn依賴項:tree -Dverbose併發布輸出,也許junit版本以某種方式不同。 – mtrovo
