我的神器似乎很大，被maven部署。我能做什麼？

Question

我的maven 3.0.3 build在Jenkins中設置了-Xmx1G和-XX:MaxPermSize=500M。然而，當我做了部署，我總是得到

神器部署是283M大。我能做些什麼才能正確部署？

Answer 1

此問題是由this bug造成的。正如鏈接中所建議的，只需使用webdav進行部署即可。

考慮執行下列操作：

<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> 

我以前有這個問題。我相信只有大於256 MB的工件纔會發生這種情況。

切換到webdav部署方法後，還可以減少內存設置。 （如果由於部署過程中的內存問題而專門修改了它們）。

這個答案只是說@olamy是正確的：升級到maven 3.0.4解決了這個問題。
