我的工件似乎很大，可以由maven部署。我能做什么？

Question

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

部署的工件283M很大。如何正确部署它？

Answer 1

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）。
