错误注入：org.apache.maven.plugin.war.WarMojo

Question

控制台打印的内容，我正在尝试在 netbeans 上运行 Java Web 应用程序，但我不太明白为什么它会给我这个错误。

解决问题的建议？？

Answer 1

从 JDK 1.8 升级到 JDK 17 后，我遇到了同样的问题，我通过升级插件版本解决了这个问题。

前：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.3</version>
</plugin>

后：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>3.3.1</version>
</plugin>

Answer 2

我有同样的问题。我正在使用 Eclipse 2021 年 6 月版。在 POM.xml 中手动配置最近的战争插件之一后，问题得到解决。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>3.3.1</version>
</plugin>

Answer 3

在 POM.xml 中手动配置 war 插件然后进行全新安装后，我的问题得到解决

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>3.3.1</version>
</plugin>

然后在终端中进行全新安装，如下所示：

mvn clean install

这应该为您提供 war 文件 (javaj22ee.war) 状态，例如：

[INFO] Building war: /Users/my_proj/java/javaj2ee/target/javaj2ee.war
[INFO]
[INFO] --- install:3.1.1:install (default-install) @ javaj2ee ---

Answer 4

您可以通过将项目中的 JDK 更改为 JDK 14 来修复此问题。左键单击您的项目并转到“属性”->“构建”->“编译”。将 JDK 更改为版本 14。如果您没有 JDK 14，可以通过单击“管理 Java 平台”来管理它。JDK的下载在这里。
