java – Jenkins Cobertura build – NoClassDefFoundError

我有一个测试类ProcessorTest与行

JSONObject jsonObj = XML.toJSONObject(convert);
DBOb = (DBObject) JSON.parse(jsonObj.toString());

XML类来自json.org.该类在代码中的其他位置使用没有问题.

在localhost上运行正常(即所有Maven和JUnit测试都执行).

当我推到Jenkins时,我得到了这个错误：

jenkins错误

我正在使用Jenkins 1.553和Cobertura插件1.9.6.

我该如何解决？

项目结构如下：

-- project1
     |
     | - core
     | - Tests (includes the tests that fail)


-- org.json
     |
     | - XML.class

当推送到Jenkins时,我假设org.json项目不可用于测试.

解决方法:

此异常和堆栈跟踪具有误导性;它实际上是因为你的类路径中没有包含SLF4J + ch.qos.logback(.ant / lib路径或ant可用的其他类路径). Cobertura(至少包括2.1.1,包括2.1.1)对ch.qos.logback SLF4J实现有特定要求.如果未包含此SLF4J实现,则可能导致以下堆栈跟踪：

java.lang.NoClassDefFoundError: net/sourceforge/cobertura/coveragedata/TouchCollector
    at [org.package.ClassName].__cobertura_init([ClassName].java)
    at [org.package.ClassName].<clinit>([ClassName].java)
    at [org.package.ClassName]Test.[method]([ClassName]Test.java:113)
Caused by: java.lang.ClassNotFoundException: net.sourceforge.cobertura.coveragedata.TouchCollector
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

在我的情况下,我已经在我的.ant / lib类路径中使用了slf4j-simple-1.7.14.jar,我需要删除它并将其替换为logback-core-1.0.13.jar和logback-classic-1.0.13.jar.之后,我的检测测试用例在没有此异常的情况下执行.
