CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:2.3.2: ArtifactResolutionException: Failure to transfer org.apache.maven.plugins:maven-compiler-plugin:pom:2.3.2 from http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-compiler-plugin:pom:2.3.2 from/to central (http://repo1.maven.org/maven2): null to http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-compiler-plugin/2.3.2/maven-compiler-plugin-2.3.2.pom..
出現這個錯誤因爲maven本地倉庫中缺少maven-resource-plugin:2.6這個相應的依賴文件。解決方法如下
在eclipse中找到maven項目下的pom.xml文件打開，並添加如下內容
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.5</version>
</plugin>
打開dos命令控制檯，進入到maven項目的目錄（包含有pom.xml文件這一層級），然後選擇 maven install 回車後發現maven會自動下載缺失的文件。
下載完成後，在eclipse中右鍵maven項目-Maven-Update Project 勾選Force Update of Snapshots/Releases這個選項，點擊OK按鈕，發現錯誤已經消失。
問題解決。
