error: goland –build constraints exclude all Go files

First,// + build will gradually replace// go: build. Both annotations can be used in go version 1.16-1.18 as the transition period. See official website https://www.jetbrains.com/help/go/configuring-build-constraints-and-vendoring.html

However,// + build cannot be used in versions below 1.16. If it is used, an error will be reported: Golan — build constraints exclude all go files.

1.16 the following versions should use// go: build

QuickFIX/J100% Java Open Source FIX Engine

http://www.quickfixj.org/
The Financial Information eXchange (FIX) protocol is a messaging standard developed specifically for the real-time electronic exchange of securities transactions. FIX is a public-domain specification owned and maintained by FIX Protocol, Ltd (FPL).
QuickFIX/J is a full featured messaging engine for the FIX protocol. It is a 100% Java open source implementation of the popular C++ QuickFIX engine.
Features:
Free! It costs nothing and has a very liberal open source licence. Full source code available (also at no cost). Supports FIX versions 4.0 – 4.4, 5.0/FIXT1.1. Runs on any hardware and operating system supported by 1.4+ Java SE or compatible VM. Compatibility with QuickFIX C++ Java Native Wrapper API (easy to upgrade)Java NIO asynchronous network communications for scalability (using Apache MINA)Supports embedded SSL with Java 5+Provides standard JMX MBeans for FIX engine management Easy to embed in existing Java applications.
Choice of message processing threading strategiesCommunication transports for TCP sockets and VM pipes. Metadata-driven parsing and validation. Metadata-driven code generation of type-safe FIX message-related classes. Metadata API for use at application level (for example, FIX messaging UI). Support for protocol customizations (new messages, fields, constraints). Session state storage plugins: JDBC, File, SleepyCat/JE, In memoryLogging plugins: JDBC, File, SFL4J (supports JDK1.4 logging, Log4J, Commons Logging), Console, Composite
Failover and High Availability. Scheduling of session connections. Many automated unit and acceptance tests. Example applications: Simple Swing order entry UI and a console-based order execution simulator. Commercial support available from multiple sources.
