编辑：我使用 spring 启动初始化程序来创建项目。
这可能是一些最新版本的 Spring-boot（然后：Spring).
我有。解决方法是在 pom.xml 中放入这个更正的依赖项：
<!-- Pour contourner un bug à la génération par Spring-boot 2.4.x :
Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources (default-resources) on project application-etude: Input length = 1 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.1.0</version>
</plugin>
异常的根本原因是某些资源包含不应过滤的资源（又名二进制文件）。正确的解决方案是为不应过滤的文件扩展名定义一个排除 like the following:
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<configuration>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>pdf</nonFilteredFileExtension>
<nonFilteredFileExtension>swf</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
</plugins>
...
</build>
...
</project>
我遇到了同样的问题并通过添加 pom.xml 解决了它：
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
这是帮助我解决问题的评论：
https://github.com/spring-projects/spring-boot/issues/24346#issuecomment-740345146
我遇到了同样的问题，并在我的 pom.xml 构建插件中使用以下更改修复了它。
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.1.0</version>
</plugin>
</plugins>
</build>
</project>
您的某些资源包含不在 ISO-8859-1 代码页中的字符，这可能会在此处引起干扰：
at java.io.Reader.read (Reader.java:229)
at org.apache.maven.shared.utils.io.IOUtil.copy (IOUtil.java:199)
典型的错误可能是 .properties 文件中的重音字符。
我认为您同时定义了 application.property 和 application.yml。如果你想同时使用它们，请尝试插入 maven-resources-plugin
在我的例子中，错误发生是因为我有使用 ANSI 编码的属性文件，而 maven 试图使用 UTF-8。我通过将我的属性文件转换为 UTF-8 来修复它，然后 运行 mvn clean compile.
在我的例子中，错误是由于重音“application.properties”
如果该工具只是给出一条消息说某个文件包含无效字符，那么修复此类错误肯定会容易得多...
备案，相关日志部分，在运行mvn clean package -e -X之后，是这个：
[DEBUG] Using 'UTF-8' encoding to copy filtered resource 'application.properties'.
[DEBUG] filtering D:\Java\PreVendaAPI\src\main\resources\application.properties to D:\Java\PreVendaAPI\target\classes\application.properties
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
<properties>
<java.version>1.8</java.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
在 application.properties 文件中使用它肯定会起作用。
您需要排除二进制资源。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.2.0</version>
<configuration>
<propertiesEncoding>UTF-8</propertiesEncoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
<nonFilteredFileExtension>xlsx</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
我有同样的错误。从我的属性文件的注释中删除德语变音符号 ('ü') 后，应该过滤掉它们，问题就消失了！
使用这个依赖解决了我的这个问题
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.2.0</version>
</dependency>
问题出在 maven-resources-plugin。这个插件的新版本没有旧版本那么宽松。不幸的是，当 Maven 构建失败（输入长度 = 1）时显示的错误消息只有在您从以前在 Java.
中遇到字符集问题的经验中识别出来时才有用。
您可以向 Maven 构建命令添加一些选项，以便它显示 DEBUG 级别的输出和构建失败时的完整堆栈跟踪。尝试将此作为诊断根本原因的第一步：
mvn -e -X clean test
在打开这些选项的情况下，它会在构建过程中向控制台输出大量信息。只需等到故障发生并检查控制台输出的结尾。你应该在最后看到一个完整的堆栈跟踪，这将更有意义。在堆栈跟踪之前，您还应该看到项目中导致错误的文件的名称。对我来说，我看到了这样的输出：
directory C:\GITROOT\conndev\repos\conn-lamp-server\src\test\resources

includes []
[DEBUG] ignoreDelta true

[INFO] ------------------------------------------------------------------------
现在我知道我的测试资源目录中的一个文件是问题所在：
src\test\resources\DummyExcelFile.xls
资源插件的旧版本一定已经悄悄地抑制了这个问题。我不会在这里包含完整的堆栈跟踪，但这是堆栈跟踪中的重要行：
Caused by: java.nio.charset.MalformedInputException: Input length = 1
我以前见过这个。当 Java 'reader' class 无法读取文本文件时会发生这种情况，因为该文件包含一个或多个对 reader 使用的字符集无效的字符。在我的例子中，它试图将二进制文件作为文本读取，所以这永远行不通！如果您的文本文件包含不寻常的字符（例如带有重音符号的欧洲语言）并且这些字符对于您使用的字符集（例如 UTF-8）无效，则可能会发生同样的问题。所有这些问题都可以通过一些POM配置来解决。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<configuration>
<propertiesEncoding>UTF-8</propertiesEncoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
<nonFilteredFileExtension>zip</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
如果您使用的是与 UTF-8 不同的字符集，只需在上面的 XML 代码段中替换您的字符集。对您希望 maven-resource-plugin 在过滤时忽略的任何文件扩展名执行相同的操作。
请注意，我有意省略了上面 maven-resources-plugin 块的 <version>。这是因为我在我的 POM 中使用 spring-boot-starter-parent 并且许多依赖项的版本是从父项继承的。如果您不使用父版本，则必须明确设置要使用的版本。
我在 application.properties 文件的注释中写入非 utf-8 字符时遇到了同样的错误。我删除了那些字符，它正在工作！
今天出现了这条消息，这是我解决它的方法：
我用mvn这样分析资源：
mvn -X process-test-resources
这样 mvn 返回了导致错误的文件的名称：
[DEBUG] filtering .../messages.properties
[INFO] ------------------------------------------------------------------------

原来 messages.properties 包含未正确转义的特殊字符。所以我在 i18n 文件中对它们进行了转义，之后我就可以再次构建了。
我不知道出了什么问题。尝试为大学项目安装 Maven。我已经按照说明安装了 maven here. Picture Environmental Variables, maven version in cmd 我还尝试删除 .m2 文件。当我尝试通过 InteliJ 中的插件安装 Maven 时，我收到消息：“进程终止”，没有额外信息。然后我尝试使用 mvn clean install 在终端上安装，我明白了。

编辑：我使用 spring 启动初始化程序来创建项目。
这可能是一些最新版本的 Spring-boot（然后：Spring).
我有。解决方法是在 pom.xml 中放入这个更正的依赖项：
<!-- Pour contourner un bug à la génération par Spring-boot 2.4.x :
Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources (default-resources) on project application-etude: Input length = 1 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.1.0</version>
</plugin>
异常的根本原因是某些资源包含不应过滤的资源（又名二进制文件）。正确的解决方案是为不应过滤的文件扩展名定义一个排除 like the following:
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<configuration>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>pdf</nonFilteredFileExtension>
<nonFilteredFileExtension>swf</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
</plugins>
...
</build>
...
</project>
我遇到了同样的问题并通过添加 pom.xml 解决了它：
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
这是帮助我解决问题的评论： https://github.com/spring-projects/spring-boot/issues/24346#issuecomment-740345146
我遇到了同样的问题，并在我的 pom.xml 构建插件中使用以下更改修复了它。
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.1.0</version>
</plugin>
</plugins>
</build>
</project>
您的某些资源包含不在 ISO-8859-1 代码页中的字符，这可能会在此处引起干扰：
at java.io.Reader.read (Reader.java:229)
at org.apache.maven.shared.utils.io.IOUtil.copy (IOUtil.java:199)
典型的错误可能是 .properties 文件中的重音字符。
我认为您同时定义了 application.property 和 application.yml。如果你想同时使用它们，请尝试插入 maven-resources-plugin
在我的例子中，错误发生是因为我有使用 ANSI 编码的属性文件，而 maven 试图使用 UTF-8。我通过将我的属性文件转换为 UTF-8 来修复它，然后 运行 mvn clean compile.
在我的例子中，错误是由于重音“application.properties”
如果该工具只是给出一条消息说某个文件包含无效字符，那么修复此类错误肯定会容易得多...
备案，相关日志部分，在运行mvn clean package -e -X之后，是这个：
[DEBUG] Using 'UTF-8' encoding to copy filtered resource 'application.properties'.
[DEBUG] filtering D:\Java\PreVendaAPI\src\main\resources\application.properties to D:\Java\PreVendaAPI\target\classes\application.properties

[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
<properties>
<java.version>1.8</java.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
在 application.properties 文件中使用它肯定会起作用。
您需要排除二进制资源。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.2.0</version>
<configuration>
<propertiesEncoding>UTF-8</propertiesEncoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
<nonFilteredFileExtension>xlsx</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
我有同样的错误。从我的属性文件的注释中删除德语变音符号 ('ü') 后，应该过滤掉它们，问题就消失了！
使用这个依赖解决了我的这个问题
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.2.0</version>
</dependency>
问题出在 maven-resources-plugin。这个插件的新版本没有旧版本那么宽松。不幸的是，当 Maven 构建失败（输入长度 = 1）时显示的错误消息只有在您从以前在 Java.
中遇到字符集问题的经验中识别出来时才有用。您可以向 Maven 构建命令添加一些选项，以便它显示 DEBUG 级别的输出和构建失败时的完整堆栈跟踪。尝试将此作为诊断根本原因的第一步：
mvn -e -X clean test
在打开这些选项的情况下，它会在构建过程中向控制台输出大量信息。只需等到故障发生并检查控制台输出的结尾。你应该在最后看到一个完整的堆栈跟踪，这将更有意义。在堆栈跟踪之前，您还应该看到项目中导致错误的文件的名称。对我来说，我看到了这样的输出：
directory C:\GITROOT\conndev\repos\conn-lamp-server\src\test\resources

[DEBUG] ignoreDelta true

现在我知道我的测试资源目录中的一个文件是问题所在：
src\test\resources\DummyExcelFile.xls
资源插件的旧版本一定已经悄悄地抑制了这个问题。我不会在这里包含完整的堆栈跟踪，但这是堆栈跟踪中的重要行：
Caused by: java.nio.charset.MalformedInputException: Input length = 1
我以前见过这个。当 Java 'reader' class 无法读取文本文件时会发生这种情况，因为该文件包含一个或多个对 reader 使用的字符集无效的字符。在我的例子中，它试图将二进制文件作为文本读取，所以这永远行不通！如果您的文本文件包含不寻常的字符（例如带有重音符号的欧洲语言）并且这些字符对于您使用的字符集（例如 UTF-8）无效，则可能会发生同样的问题。所有这些问题都可以通过一些POM配置来解决。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<configuration>
<propertiesEncoding>UTF-8</propertiesEncoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
<nonFilteredFileExtension>zip</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
如果您使用的是与 UTF-8 不同的字符集，只需在上面的 XML 代码段中替换您的字符集。对您希望 maven-resource-plugin 在过滤时忽略的任何文件扩展名执行相同的操作。
请注意，我有意省略了上面 maven-resources-plugin 块的 <version>。这是因为我在我的 POM 中使用 spring-boot-starter-parent 并且许多依赖项的版本是从父项继承的。如果您不使用父版本，则必须明确设置要使用的版本。
我在 application.properties 文件的注释中写入非 utf-8 字符时遇到了同样的错误。我删除了那些字符，它正在工作！
今天出现了这条消息，这是我解决它的方法：
我用mvn这样分析资源：
mvn -X process-test-resources
这样 mvn 返回了导致错误的文件的名称：
[DEBUG] filtering .../messages.properties
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE

原来 messages.properties 包含未正确转义的特殊字符。所以我在 i18n 文件中对它们进行了转义，之后我就可以再次构建了。
