英文:
error: invalid source release 14 with --enable-preview
问题
我正在使用Micronaut 2.0.2应用程序与IntelliJ IDE 2020.2.2。我已在IDE中从语言级别启用了预览功能。
在Gradle文件中，我有以下选项：
java {
sourceCompatibility = JavaVersion.toVersion('14')
targetCompatibility = JavaVersion.toVersion('14')
}
tasks.withType(JavaCompile) {
options.encoding = "UTF-8"
options.compilerArgs.addAll([
'-parameters',
// 启用增量编译
'-Amicronaut.processing.incremental=true',
'-Amicronaut.processing.annotations=fete.bird.*',
"-Amicronaut.processing.group=$project.group",
"-Amicronaut.processing.module=$project.name",
"--enable-preview"
])
}
出现错误：error: invalid source release 14 with --enable-preview。
英文:

])
}
Getting an error as error: invalid source release 14 with --enable-preview

如果您的 pom.xml 中有一些错误的配置，类似这样的，请将其删除。在我删除这些配置后，它对我起效了：
<configuration>
<source>15</source>
<target>15</target>
<compilerArgs>--enable-preview</compilerArgs>
</configuration>
这就是对我造成干扰的部分。因为我已经安装了 Java 16。
英文:
If you have some wrong configurations in your pom.xml like this remove it. It worked for me after I remove the configs:
<configuration>
<source>15</source>
<target>15</target>
<compilerArgs>--enable-preview</compilerArgs>
</configuration>
That's what was messing up for me. Since I already have Java 16 already.
