如何解決這些Maven錯誤：類路徑錯誤：無法找到..，ArtifactDescriptorException：無法讀取工件描述符

Question

我試圖使用Springsource工具套件（STS），但我有這麼多的編譯錯誤。

classpath error: unable to find org.aspectj.lang.JoinPoint (check that aspectjrt.jar is in your classpath) SpringApp  Unknown Java Problem 

ArtifactDescriptorException: Failed to read artifact descriptor for cglib:cglib-nodep:jar:2.2: ArtifactResolutionException: Failure to transfer cglib:cglib-nodep:pom:2.2 from http://maven.springframework.org/release was cached in the local repository, resolution will not be reattempted until the update interval of spring-maven-release has elapsed or updates are forced. Original error: Could not transfer artifact cglib:cglib-nodep:pom:2.2 from/to spring-maven-release (http://maven.springframework.org/release): null to http://maven.springframework.org/release/cglib/cglib-nodep/2.2/cglib-nodep-2.2.pom pom.xml /SpringApp line 1 Maven Dependency Problem 

Failure to transfer org.codehaus.mojo:aspectj-maven-plugin:pom:1.2 from http://maven.springframework.org/release was cached in the local repository, resolution will not be reattempted until the update interval of spring-maven-release has elapsed or updates are forced. Original error: Could not transfer artifact org.codehaus.mojo:aspectj-maven-plugin:pom:1.2 from/to spring-maven-release (http://maven.springframework.org/release): null to http://maven.springframework.org/release/org/codehaus/mojo/aspectj-maven-plugin/1.2/aspectj-maven-plugin-1.2.pom pom.xml /SpringApp line 1 Maven pom Loading Problem 

我發現這麼多的問題在這裏在stackoverflow，但沒有答案。

Answer 1

我只是設置了IDE的代理設置以及Maven的setings.xml代理設置。
