Answer 1

TL; DR

从<classifier>exec</classifier>

的依赖项中删除com.conduiraonline:licenseapi

更多详情......

使用<dependency>来表达com.conduiraonline:contentmanagementapi和com.conduiraonline:licenseapi之间的关系是正确的。或者用另一种方式;这是正确的方式告诉Maven模块com.conduiraonline:contentmanagementapi取决于模块com.conduiraonline:licenseapi。

但是，您已将com.conduiraonline:licenseapi的依赖关系定义为：

    <dependency>
        <groupId>com.conduiraonline</groupId>
        <artifactId>licenseapi</artifactId>
        <version>0.0.1</version>
        <classifier>exec</classifier>
    </dependency>

classifier告诉Maven在本地Maven仓库中的licenseapi.exec文件夹中查找名为com/conduiraonline的文件（如果失败了，请尝试从任何远程存储库中解析该依赖关系已在Maven settings.xml或此pom.xml中配置。）

我认为本地Maven仓库中的文件夹licenseapi.exec中没有名为com/conduiraonline的文件，因为exec是Maven工件的一个非常不寻常的分类器。

只要在您的本地Maven仓库中安装了版本为com.conduiraonline:licenseapi的{{1}}的JAR，此依赖关系就会起作用：

0.0.1

通过为<dependency> <groupId>com.conduiraonline</groupId> <artifactId>licenseapi</artifactId> <version>0.0.1</version> </dependency>模块运行com.conduiraonline:licenseapi，在本地Maven仓库中为版本为0.0.1的{{1}}安装JAR（假设{的pom.xml为{ {1}}个模块有mvn clean install）。

Answer 2

您必须在gradle或maven构建文件中添加包含jar的jar /文件夹的路径。

例如在gradle中添加

    compile fileTree(dir: 'path_to_ext_libs', include: '*.jar')

到build.gradle中的依赖项，然后将包含libs文件夹中的所有jar文件。

或在maven中

<repositories>
   <repository>
     <id>local-files</id>
     <name>local-files</name>
     <url>file://c:\test\filerepo</url>
  </repository>
