私はEclipseでMaven2プロジェクトに取り組んでおり、m2eプラグインを持っていますが、Eclipseで次のエラーが発生します。
Failure to transfer com.thoughtworks.xstream:xstream:pom:1.3.1 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 com.thoughtworks.xstream:xstream:pom:1.3.1 from/to central (http://
repo1.maven.org/maven2): Failed to create a selector. to http://repo1.maven.org/maven2/com/thoughtworks/xstream/
xstream/1.3.1/xstream-1.3.1.pom
修正方法を教えてください。
