定制maven测试类路径/类加载器序列

maven

定制maven测试类路径/类加载器序列,maven,classpath,Maven,Classpath,我想更改maven中类路径项的顺序，以确保资源（特别是log4.properties）按照我的规范的确定顺序获取 maven目前生成的类路径没有明显的韵律/原因。这里的目的是在默认maven生成的类路径前面加上resources目录： classpath=<resources directory>:$MAVEN_DEFAULT_CLASSPATH 如何实现这一点？最好使用pom.xml中的选项，并通过maven命令行上的“-D”参数实现 这里的任务是通过SCASTATEST运行测

我想更改maven中类路径项的顺序，以确保资源（特别是log4.properties）按照我的规范的确定顺序获取

maven目前生成的类路径没有明显的韵律/原因。这里的目的是在默认maven生成的类路径前面加上resources目录：

 classpath=<resources directory>:$MAVEN_DEFAULT_CLASSPATH
如何实现这一点？最好使用pom.xml中的选项，并通过maven命令行上的“-D”参数实现

这里的任务是通过SCASTATEST运行测试：我们可以考虑它与Maven SuffFi火插件有关。我将再次检查scalatest是否重用maven surefire类路径

更新：让我们澄清一下maven为类路径实际生成了什么：

/Users/steve/.m2/repository/org/apache/hadoop/hadoop-hdfs/2.2.0/hadoop-hdfs-2.2.0-tests.jar:
/Users/steve/.m2/repository/com/twitter/parquet-column/1.6.0rc3/parquet-column-1.6.0rc3.jar:
/Users/steve/.m2/repository/org/spark-project/akka/akka-slf4j_2.10/2.3.4-spark/akka-slf4j_2.10-2.3.4-spark.jar:
/Users/steve/.m2/repository/com/google/protobuf/protobuf-java/2.5.0/protobuf-java-2.5.0.jar:
/Users/steve/.m2/repository/com/codahale/metrics/metrics-json/3.0.0/metrics-json-3.0.0.jar:
/Users/steve/.m2/repository/org/tachyonproject/tachyon-client/0.5.0/tachyon-client-\

etc ..
正如我们所看到的，我们没有遵循预期的类路径结构——即先有资源目录

根据评论员的建议，添加了另一个更新mvn-X，以下是与surefire和scalatest相关的更详细输出的摘录：

${surefire.parallel.forcedTimeout}在哪里需要类路径？在maven surefire plugin/maven failsafe plugin？@khmarbaise好问题：我已经更新了OPIf，如果您通过maven surefire plugin运行测试，那么文件夹
src/test/resources
或者更准确地说
target/test classes
是类路径上的第一个文件夹，之后将是
src/test/java/
/src/main/resources
（target/classes`。就是这样定义的。我可能误解了你的问题吗？@khmarbaise你完全理解这个问题：你的“答案”是我所期望的。但是，实际的类路径（如我添加的打印语句所示）与此大不相同，事实上，在这些资源目录之前放置了一堆不重要的jar文件。顺便说一句，我更新了OP，以根据您在此处的良好评论进行澄清。您可以通过
mvn-X
检查输出，并在那里搜索
测试类路径：
，然后您将看到您正在搜索的内容。
