在Maven target和Maven repository中都找到了Liquibase资源

Question

我有Eclipse Maven GWT项目，并且添加了使用LiquiBase的flowable-form-engine依赖项。Liquibase正在搜索变更日志文件org/flowable/form/db/Liquibase/flowable-form-db-changelog.xml，但发现了两个！

所以我调试了它,它从目标目录中找到了一个资源：

jar:file:/C:/work/git/coarui/target/Main-1.0-SNAPSHOT/WEB-INF/lib/flowable-form-engine-6.4.0.jar!/org/flowable/form/db/liquibase/flowable-form-db-changelog.xml

和其他资源：

jar:file:/C:/Users/Piro/.m2/repository/org/flowable/flowable-form-engine/6.4.0/flowable-form-engine-6.4.0.jar!/org/flowable/form/db/liquibase/flowable-form-db-changelog.xml

是否有方法忽略其中之一，或者是我的构建路径或依赖项定义错误？

我的生成路径包含：

null

<dependency>
  <groupId>org.flowable</groupId>
  <artifactId>flowable-form-engine-configurator</artifactId>
  <version>${flowableVersion}</version>
</dependency>

Maven GWT插件groupid=net.ltgt.GWT.Maven,artifactid=gwt-maven-plugin具有配置参数classpathscope，但我测试了 compile+runtime 、 compile 和 runtime 并发生了相同的错误。

在网上搜索，我在flowable forum（1,2）上找到了类似的帖子，但没有提供解决方案。

由于某种原因，您的.m2似乎在类路径中。如果它对您确实有意义，那么您可以尝试在pom中使用 提供的 ，在pom中声明对flowable-form-engine-configurator的依赖关系。但是，您可以决定将.m2从类路径中排除，我认为这样更好。
