java - Jenkins 插件无法使用 java8 进行编译，因为无法识别流类

我正在尝试使用 mvn install -Dmaven.test.skip=true 构建 Jenkins 插件，但失败并出现以下错误:

[INFO] --- animal-sniffer-maven-plugin:1.15:check (check) @ osf-builder-suite-for-sfcc-deploy ---

[ERROR] .../DeployBuilder.java:609: Undefined reference: boolean java.util.stream.Stream.anyMatch(java.util.function.Predicate)

我已在我的 pom 中将 java 级别设置为 8。

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>${jdk.version}</source>
                <target>${jdk.version}</target>
                <optimize>true</optimize>
            </configuration>
        </plugin>

知道为什么它仍然尝试验证/编译 java7 和流类无法识别吗？

我该怎么做才能让它正常工作？

最佳答案

您必须将嗅探器的签名设置为java 1.8

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>animal-sniffer-maven-plugin</artifactId>
    <version>1.16</version>
    ...
    <configuration>
      ...
      <signature>
        <groupId>org.codehaus.mojo.signature</groupId>
        <artifactId>java18</artifactId>
        <version>1.0</version>
      </signature>
      ...
    </configuration>
    ...
  </plugin>

如果我有一个带有 <artifactId>java17</artifactId> 的签名我在我的一个类中使用流，嗅探器会提示，因为流不是 java 1.7 的一部分

如果我随后将签名更改为 <artifactId>java18</artifactId> ，嗅探器将不再提示:

关于java - Jenkins 插件无法使用 java8 进行编译，因为无法识别流类，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45997103/
