Maven：无效的目标版本：10

时间：2018-07-22 19:25:21

标签： java maven pom.xml java-10

我正在尝试使用maven编译我的Java 10项目，但是遇到了麻烦。在我的IDE（IntelliJ IDEA）中，所有内容都可以在Java 10下编译并正常运行。我安装了最新的maven版本3.5.4，并将我的JAVA_HOME指向JDK 10：

$ mvn --version
Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T20:33:14+02:00)
Maven home: C:\Maven\bin\..
Java version: 10.0.2, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk-10.0.2
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

我使用的maven命令是：

mvn package -Dmaven.test.skip

在我的pom.xml中，Java 8具有以下功能，效果很好：

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <libraries.directory>libraries</libraries.directory>
</properties>

对于Java 10，我将其更改为以下内容：

<maven.compiler.source>10</maven.compiler.source>
<maven.compiler.target>10</maven.compiler.target>

这不起作用，就像使用1.10作为源编译器和目标编译器的版本一样。

完整的调试日志记录输出（-X命令行开关）如下：

添加this答案中所建议的maven-compiler-plugin也不起作用：

Fatal error compiling: invalid flag: --release -> [Help 1]

关于如何解决此问题的任何想法？

6 个答案:

答案 0 :(得分：12)

通过将JAVA_HOME环境变量设置为指向具有正确版本的JDK，为我解决了相同的问题。

我在maven-compiler-plugin中的源Java和目标Java版本是11，java -version也在11版本上，但是我的JAVA_HOME指向JDK-1.8。

使用终端而不是IDE再次检查JAVA_HOME：

Linux:
echo $JAVA_HOME

Win:
echo %JAVA_HOME%

然后在同一终端中构建项目：

mvn clean package

答案 1 :(得分：9)

这对我有用：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>
                <release>10</release>
            </configuration>
        </plugin>
    </plugins>
</build>

此answer说，您需要：

<dependencies>
    <dependency>
        <groupId>org.ow2.asm</groupId>
        <artifactId>asm</artifactId>
        <version>6.2</version> <!-- Use newer version of ASM -->
    </dependency>
</dependencies>

在<plugin/>标记内，但是较新的mvn（3.5.4）必须避免，因为我不需要它。

答案 2 :(得分：5)

Spring Boot和Java 11也有类似的问题。 我通过在pom中定义以下属性来解决了该问题

import SwiftUI

struct ContentView: View {
    @State private var isShowingModal = false

    var body: some View {
        GeometryReader { geometry in
            ZStack {
                Button(
                    action: { withAnimation { self.isShowingModal = true } },
                    label: { Text("Show Modal") }
                )

                ZStack {
                    if self.isShowingModal {
                        ModalOverlay(tapAction: { withAnimation { self.isShowingModal = false } })
                        ModalContent().transition(.move(edge: .bottom))
                    }
                }.edgesIgnoringSafeArea(.all)
            }
        }
    }
}

struct ModalOverlay: View {
    var color = Color.black.opacity(0.4)
    var tapAction: (() -> Void)? = nil

    var body: some View {
        color.onTapGesture { self.tapAction?() }
    }
}

struct ModalContent: View {
    var body: some View {
        GeometryReader { geometry in
            VStack {
                Spacer()
                VStack(spacing: 16) {
                    Text("Item 1")
                    Text("Item 2")
                    Text("Item 3")
                }
                .frame(width: geometry.size.width)
                .padding(.top, 16)
                .padding(.bottom, geometry.safeAreaInsets.bottom)
                .background(Color.white)
            }
        }
    }
}

将来可能对某人有用。

答案 3 :(得分：3)

这意味着您正在使用尚未安装的java.version 10。

<properties>
    <java.version>10</java.version>
</properties>

答案 4 :(得分：1)

有时它只是您的Java版本。例如，当项目使用Java 10但Java路径设置为8时，等等。尝试运行java -version并确保它与您的项目相同。如果没有，请修复它，然后重试。

答案 5 :(得分：0)

通过运行java -version获取Java版本。

您将获得类似输出：

java version "1.8.0_201"

现在转到您的POM文件，并使用已安装的Java版本更新maven-compiler-plugin的源和目标属性。在我的情况下是1.8 

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-compiler-plugin</artifactId>
   <configuration>
      <source>1.8</source>
      <target>1.8</target>
   </configuration>
</plugin>
