我像这样使用maven导入项目中的依赖项:
<dependency>
<groupId>de.javakaffee</groupId>
<artifactId>kryo-serializers</artifactId>
<version>0.45</version>
</dependency>
但是该项目提供了此提示(文件网址:https://mvnrepository.com/artifact/de.javakaffee/kryo-serializers/0.45):
Dependency 'de.javakaffee:kryo-serializers:0.45' not found.
我已经尝试过了:
mvn clean install -e -U
然后reimoprt pom.xml。然后我换成另一个jar,就可以了。就像这样:
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.58</version>
</dependency>
这是我的settings.xml配置:
<repositories>
<repository>
<id>central</id>
<name>central repository</name>
<url>https://repo1.maven.org/maven2</url>
<layout>default</layout>
<releases>
<enabled>true</enabled>
<updatePolicy>never</updatePolicy>
</releases>
<snapshots>
<enabled>true</enabled>
<updatePolicy>never</updatePolicy>
</snapshots>
</repository>
<repository>
<id>snapshots</id>
<name>Snapshots</name>
<snapshots>
<enabled>true</enabled>
<updatePolicy>never</updatePolicy>
<checksumPolicy>fail</checksumPolicy>
</snapshots>
<url>https://nexus.myrepo.com/repository/maven-snapshots/</url>
</repository>
<repository>
<id>releases</id>
<name>Releases</name>
<snapshots>
<enabled>false</enabled>
</snapshots>
<url>https://nexus.myrepo.com/repository/maven-releases/</url>
</repository>
</repositories>
问题是:为什么同一个仓库,有的jar导入成功,有的失败?哪里出了问题?
