無法在Eclipse Oxygen和Java 9中創建/導入Gradle（4.3）項目

Question

我正在嘗試使用Eclipse Oxygen在Gradle和Spring Boot中開發項目。 我有最新的Gradle版本。 我的系統在MAC 10.10.2（14C109）OS X Yosemite中。

以下是有關該問題的詳細信息。 在創建項目時，Gradle用戶主目錄在我所附的圖像的最后一頁上為“未知”：

$gradle -version

注意不確定有什么幫助，但是可以解決。 我做了兩件事：1.我在Eclipse的工作區中從終端運行gradle命令。 2.從Eclipse IDE更新了Buildship Gradle集成。

Answer 1

Buildship團隊發布了一個里程碑式的2.2版本，以解決此問題。

您可以在Eclipse中安裝里程碑2.2。 幫助>安裝新軟件...>使用： http : //download.eclipse.org/buildship/updates/e47/milestones/2.x >選擇最新版本>完成

或者，您可以等到Buildship的2.2正式發布並更新Buildship插件。

里程碑公告： https : //discuss.gradle.org/t/buildship-2-2-milestone-is-now-available/24551

Answer 2

您必須從Eclipse Marketplace安裝Buildship，並且還更改了構建腳本（以將具有意外行為的gradle eclipse插件修復為Java 9）：

eclipse {
    jdt.file.withProperties { props ->
       props.put('org.eclipse.jdt.core.compiler.codegen.targetPlatform', '9')
       props.put('org.eclipse.jdt.core.compiler.source', '9')
       props.put('org.eclipse.jdt.core.compiler.compliance', '9')
    }
    classpath.defaultOutputDir = new File(buildDir, "classes/main")
}
