使用GradleMaven插件时如何设置java目标和源版本？

我正在为gradle使用Gradle3.5和maven插件

我有一个生成pom.xml的任务，由于源和目标版本的java，生成的pom是错误的

这为1.5生成了pom.xml（错误）：

这是添加

build

对象时的输出错误：

* What went wrong:
Execution failed for task ':createPom'.
> No such property: _SCRIPT_CLASS_NAME_ for class: org.apache.maven.model.Model

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

我就是这样解决目标和源问题的：

pom {
    project {
        groupId 'com.domain.api'
        artifactId 'gs-gradle'
        version '0.1.0'
        properties {
            project {
                build {
                    sourceEncoding 'UTF-8'
                }
            }
            maven {
                compiler {
                    source '1.8'
                    target '1.8'
                }
            }
        }

        inceptionYear '2008'
        licenses {
            license {
                name 'The Apache Software License, Version 2.0'
                url 'http://www.apache.org/licenses/LICENSE-2.0.txt'
                distribution 'repo'
            }
        }
    }
}

这样我就可以设置属性了

如果您确实需要自定义

构建

，您将无法以相同的方式声明它，因为负责它的插件。这是您可以做到的：

pom {
    project {
        groupId 'com.domain.api'
        artifactId 'gs-gradle'
        version '0.1.0'
        properties {
            project {
                build {
                    sourceEncoding 'UTF-8'
                }
            }
            maven {
                compiler {
                    source '1.8'
                    target '1.8'
                }
            }
        }

        inceptionYear '2008'
        licenses {
            license {
                name 'The Apache Software License, Version 2.0'
                url 'http://www.apache.org/licenses/LICENSE-2.0.txt'
                distribution 'repo'
            }
        }
    }
}.withXml {
    asNode().appendNode('build').appendNode('plugins').with {
        appendNode('plugin').with {
            appendNode('groupId', 'org.springframework.boot')
            appendNode('artifactId', 'spring-boot-maven-plugin')
            appendNode('version', "${springBootVersionDef}")
            appendNode('executions').appendNode('execution').appendNode('goals').with {
                appendNode('goal', 'repackage')
            }
        }
        appendNode('plugin').with {
            appendNode('groupId', 'org.apache.maven.plugins')
            appendNode('artifactId', 'maven-jar-plugin')
            appendNode('version', "3.0.2")
            appendNode('configuration').appendNode('archive').appendNode('manifest').with {
                appendNode('addClasspath', "true")
                appendNode('classpathPrefix', "lib/")
                appendNode('mainClass', "com.domain.api.Application")
            }
        }
    }
}.writeTo("pom.xml")

当您尝试构建时，是否收到来自gradle的错误消息？
