Gradles maven发布插件在发布大文件（350MB）时消耗堆（1GB）

我正在使用maven发布插件向Sonatype Nexus发布许多工件。大多数这些工件的大小都小于10Mb，并且都可以很好地发布

然而，其中一个伪影约为350Mb。当我试图发布它时，我得到了以下输出：我的雇主可能不喜欢我在网上发布的名字

我在VisualVM中观察了这个运行，看到在抛出这个异常之前，当我使用-Xmx1G运行时，堆从~100Mb快速地尖峰到>1Gb

堆转储表明内存是由lightweightHttpWang使用的sun.net.www.http.PosterOutputStream分配的

我在Gradle版本1.8、1.10和2.0中尝试过这一点

还有谁见过这个吗

有任何修复/解决方法吗

我的脚本如下所示：

apply plugin: 'maven-publish'

task publishAsZip(type: Zip) {
    if (!rootProject.hasProperty('releaseRoot')) {
        println 'The release root directory has not been specified - skipping task'
    } else {
        from new File(targetRoot, "files")
        baseName 'app'
        destinationDir  new File(releaseRoot, "Build $jenkinsBuildNumber")
        version  "${appVersion}-win-${jenkinsBuildNumber}"

        publishing {
            publications {
                releaseArtifact(MavenPublication) {
                    groupId 'blah.blah.blah'
                    artifactId 'blah-app'
                    version "1.3.${jenkinsBuildNumber}"
                    artifact publishAsZip
                }
           }
            repositories {
                maven {
                    credentials {
                        username 'deploymentUser'
                        password 'deploymentPass'
                    }
                    url "http://nexusserver:8081/nexus/content/repositories/snapshots/"
                }
            }
        }
    }
}

最后，我使用WebDav将其部署到Nexus：

apply plugin: 'java'
apply plugin: 'maven'

configurations {
    ...
    wagonJars
}

dependencies {
    ...
    wagonJars 'org.apache.maven.wagon:wagon-webdav-jackrabbit:2.7'
}

task buildRelease(type: Zip) {
    ...
}

artifacts {
    archives buildRelease
}

uploadArchives {
    repositories.mavenDeployer {
        configuration = configurations.wagonJars
        repository(url: 'dav:http://.../') {
            authentication(userName: '...', password: '...')
        }
        pom.groupId = '...'
        pom.artifactId = '...'
        pom.version = "..."
    }
}

我遇到了一个约270mb文件的问题。我通过将GradleRapper升级到gradle 2.11的最新版本来修复它。

找到解决方法了吗？找到了！看到我下面的答案…对，所以使用旧的maven插件而不是新的maven发布插件，谢谢。太好了！很高兴知道他们已经修好了。
