我的Maven 3.0.3版本在Jenkins中设置了-Xmx1G和-XX:MaxPermSize=500M。但是,当我进行部署时,我总是
-Xmx1G
-XX:MaxPermSize=500M

部署的工件283M很大。如何正确部署它?
283M
此问题是由此bug引起的。如链接中所建议,只需使用webdav进行部署。
考虑执行以下操作:
<project> [...] <build> <extensions> <extension> <groupId>org.apache.maven.wagon</groupId> <artifactId>wagon-webdav</artifactId> <version>1.0</version> </extension> </extensions> </plugin> </build> ... <distributionManagement> <site> <id>sample-project.website</id> <url>dav:https://dav.sample.com/sites/sample-project</url> </site> </distributionManagement> ... </project>
我以前有过这个问题。我相信只有在大小大于等于256 MB的工件时才会发生这种情况。
切换到webdav部署方法后,您还可以减少内存设置。(如果您只是由于部署过程中的内存问题而专门修改了它们)。
