我有一个使用maven-war-plugin构建的Web应用程序

<plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-war-plugin</artifactId>
                    <configuration>
                        <webResources>
                            <resource>
                                <directory>${project.build.directory}/min</directory>
                            </resource>
                        </webResources>
                    </configuration>
                </plugin>

当我运行maven clean package时,构建运行良好,但是maven抱怨插件没有版本。所以我将版本添加到插件中,它变成了

 <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-war-plugin</artifactId>
                    <version>3.2.2</version>
                    <configuration>
                        <webResources>
                            <resource>
                                <directory>${project.build.directory}/min</directory>
                            </resource>
                        </webResources>
                    </configuration>
                </plugin>

这次我遇到OOM错误

Caused by: java.lang.OutOfMemoryError: Java heap space
at org.codehaus.plexus.archiver.zip.ByteArrayOutputStream.needNewBuffer (ByteArrayOutputStream.java:153)
at org.codehaus.plexus.archiver.zip.ByteArrayOutputStream.write (ByteArrayOutputStream.java:192)

at org.apache.commons.compress.archivers.zip.StreamCompressor.writeCounted (StreamCompressor.java:273)

我添加了<argLine>-Xmx1024m</argLine>并更改了MAVEN_OPTS,但这些帮助都没有。

我的问题:为什么版本号很重要,如果我不包括它,那又是什么问题呢?为什么即使添加Xmx也会发生这种OOM?谢谢!

P.S。,当我不指示version时,如果有帮助,maven使用2.2作为war插件。
