MavenReportException: Error while generating Javadoc: Unable to write 'options' temporary file for command execution: Input length = 1

[QuantityIntel]

I have the error above.

$ java -version openjdk version "17.0.2" 2022-01-18 OpenJDK Runtime Environment Temurin-17.0.2+8 (build 17.0.2+8) OpenJDK 64-Bit Server VM Temurin-17.0.2+8 (build 17.0.2+8, mixed mode, sharing)

$ mvn -version Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0) Maven home: C:\dev\apache-maven-3.8.5 Java version: 17.0.2, vendor: Eclipse Adoptium, runtime: C:\Program Files\Eclipse Adoptium\jdk-17.0.2.8-hotspot Default locale: ko_KR, platform encoding: MS949 OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

What should I do?

[tsaglam]

What version of JPlag are you trying to build? Which mvn command did you run? We are not on Java 17 yet, so I have not tried building JPlag with Java 17 yet.

I'm trying to build v3.0.0.
I ran the command mvn clean package
Which version of Java would be compatible?

[tsaglam]

I have tested building v3.0.0 with Java 17 and works fine for me on my system.
Maybe try mvn clean package -U. If it does not work please provide:

• the full CLI output of mvn clean package
• the output of mvn -version

@Jiseong-Michael-Yang do you have docker? Then you could test whether the compilation works within docker on your machine.
I've just tested the compilation process within the following docker image: maven:3.8.4-eclipse-temurin-17 (v.3.8.5 hasn't released for docker so far)

Could you please run maven package with debug option to get more insights.

[tsaglam]

A workaround is to disable the maven javadoc plugin plugin in the pom.xml in the main project directory.
