根据Java Exec allJvmArgs属性javadoc,allJvmArgs是
List<String> allJvmArgs
The full set of arguments to use to launch the JVM for the process. This includes arguments to define system properties, the minimum/maximum heap size, and the bootstrap classpath.
我试图使用此属性失败.以下是我的尝试.
示例Java代码.
// SRC /主/ JAVA / COM /例子
package com.examples;
public class AllJvmArgumentsInJavaExecBug {
public static void main(String[] args) {
System.out.println("Hello From Java");
}
}
// File: build.gradle
apply plugin: 'java'
task(runJavaExecNormal, dependsOn: 'classes', type: JavaExec) {
main = 'com.examples.AllJvmArgumentsInJavaExecBug'
classpath = sourceSets.main.runtimeClasspath
}
task(runJavaExecArgumentSetExample1, dependsOn: 'classes', type: JavaExec) {
main = 'com.examples.AllJvmArgumentsInJavaExecBug'
classpath = sourceSets.main.runtimeClasspath
allJvmArgs = [ '-Xms10240m', '-Xmx20280m']
}
task(runJavaExecArgumentSetExample2, dependsOn: 'classes', type: JavaExec) {
main = 'com.examples.AllJvmArgumentsInJavaExecBug'
classpath = sourceSets.main.runtimeClasspath
List<String> argumentList = new ArrayList<String>();
argumentList.add('-Xms10240m')
argumentList.add('-Xmx20280m')
allJvmArgs = argumentList
}
我得到以下错误.

我无法使用此属性.
我可以使用maxHeapSize =“2g”,如question所示.
我想用它来设置最小堆大小.
以下是github project,它重现了这种情况.
解决方法:
来自org.gradle.process.internal.JavaExecHandleBuilder的源代码包含:
public void setAllJvmArgs(Iterable<?> arguments) {
throw new UnsupportedOperationException();
}
你应该能够使用jvmArgs而不是allJvmArgs.
