Question

当我尝试启动nexus时，我一直收到此错误。

Error installing bundle listed in startup.properties with url: mvn:org.ops4j.pax.url/pax-url-aether/2.4.7 and startlevel: 1
        java.lang.NullPointerException

如何解决这个问题？

Answer 1

您确定dists = pdist2( A(:,2), B(:,2) ); % Set values which are greater than the row/column minima to be infinity. % This means they will never be within the tolerance of 20 (or whatever else) dists ( bsxfun(@gt, dists, min(dists,[],1)) | bsxfun(@gt, dists, min(dists,[],2)) ) = Inf; % In MATLAB versions > 2016b, you can use implicit expansion to replace bsxfun % That would be: dists( dists > min(dists,[],1) | dists > min(dists,[],2) ) % Now continue as before [iA, iB] = find( dists < 20 ); C = A(iA, :); D = B(iB, :);文件夹的文件权限是否正确？我遇到了类似的错误，其中nexus/system归nexus/system所有，而root则是我用来运行Nexus的用户。

我通过运行nexus解决了我的问题。

使用url安装startup.properties中列出的软件包时出错：mvn：org.ops4j.pax.url / pax-url-aether / 2.4.7
